Using Newton’s second law we can estimate the average force acting on the ball during the hit: Plugging in the numbers we find the average force to be
F
avg
=18,436 N
, which is equivalent to 4124 lbs of force.
How do you find force exerted on a ball?
The force formula is defined by Newton’s second law of motion: Force exerted by an object
equals mass times acceleration of that object: F = m ⨉ a
. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
How do you calculate average force exerted?
Formula for Average Force
The mass of the object multiplied by the average velocity over the definite time is equal to the average force
. For a specific interval of time t, the force is explained as the frequency of change of momentum.
What is the average force exerted on the object?
The average force is
the force exerted by some object moving at some defined rate of speed
i.e. velocity for a defined period of time. The word average here is used to indicate that this is not an instantaneous or precisely measured velocity.
What average force was exerted on the object during this period of acceleration?
Answer: Average force was exerted on the object during this period of acceleration is
2.952 N
. Answer: Average force was exerted on the object during this period of acceleration is 2.952 N.
How do you find the average force a ball applies to a wall?
Since the velocity of the ball just as it first touches the wall is known (vi), the velocity of the ball at maximum compression against the wall is known (vf=0), and the distance moved during the compression against the wall is known (“r-d”), you can calculate the average acceleration from the formula
v2f=v2i+2aΔx
, …
What forces act on a ball?
The forces are the
weight, drag, and lift
. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion.
What force pushes a ball up?
The ball falls;
gravity
pulls it down, so it speeds up, while air drag somewhat slows the fall. When the ball hits the ground a huge normal force pushes upwards, making the ball bounce not quite as high as when it started.
What forces are acting on a ball on the floor?
There are two forces acting on the ball:
tension from the string and force due to gravitation
.
What is the magnitude of the average force exerted by the ball on the bat?
The huge force exerted by the bat on the ball causes severe distortion of the ball as it is hit. So, during the bat-ball collision, an average force of
roughly two tons
acts during the 0.7 millisecond contact time, with a peak force of about four tons. That’s a lot of force!
What is the magnitude of the average force exerted by the bat on the ball answer in units of N?
The magnitude of the average force exerted on the bat is
173.3 N
.
What average force is necessary to stop a bullet?
So [
5.2kN]
force required to stop the bullet.
Is average force the same as net force?
As an example if you have a two second time period in which the first second there was 2 newtons of force, and the second there was 0 newtons of force, your average force would be 1 newton per second, even though there was never 1 newton of force applied to the object.
Net force is a sum value
.
Is impulse A average force?
Impulse ( F Δ t F Delta t FΔt )
Product of
the average force exerted on an object
and the time interval during which the force is exerted. Impulse is equal to the change in momentum ( Δ p Delta p Δp ) and is sometimes represented with the symbol J.
How do you find the average force of a collision?
The most straightforward way to approach the concept of average force is
to multiply the constant mass times the average acceleration
, and in that approach the average force is an average over time. Another approach that is valuable for assessing the impact force in high speed collisions is to use the impulse of force.
How do you find the average force on a force time graph?
The average force is found by
taking the area under the force vs. time curve and dividing by the time
(the base of the triangle in this case).
How do you calculate the average force of friction?
- Choose the normal force acting between the object and the ground. Let’s assume a normal force of 250 N .
- Determine the friction coefficient. …
- Multiply these values by each other: (250 N) * 0.13 = 32.5 N .
- You just found the force of friction!
What is the forces exerted by the rolls?
When the ball rolls on the ground, the ground exerts
a friction force
on the ball in the opposite direction of its motion. Due to this friction force, the ball retards (gets slowed down) and finally stops after some time covering small distance.
What average force is needed to accelerate a 7.00 g pellet from rest to 125 m/s over a distance of 0.800 m along the barrel of a rifle?
Force F=68.4N
.
What force was exerted by the ball and the table?
One is
gravity
on the ball, the other is the ball on the table. The first is Newton’s Universal Gravitation. The force is due to mutual attraction. The ball is pulling on the Earth, and the Earth is pulling on the ball.
How is the strength of the force expressed?
The strength of the force is expressed by
its magnitude
. The magnitude of force is represented in the SI unit of force called newton. One newton is force which can make an object of one-kilogram weight to move at a speed of one meter per second. … Therefore, the correct option is force is expressed by magnitude.
What is magnitude of average force?
The word ‘average’ is used to indicate that this is not an ‘instantaneous’ or precisely measured velocity. Thus, average Force is
equal to the mass of the body multiplied by the average velocity over the defined time
.
What happens to the baseball bat when it hits a ball?
A significant portion of the initial kinetic energy was lost to friction forces during the compression and relaxation of the ball while is distorts during impact. … During the
collision the barrel of the bat compresses and expands
, appearing to throw the ball away.
How does the force of the bat on the ball compare to the force the ball exerts on the bat?
Explanation: According to Newton’s third law, the force exerted by the bat hitting the ball will be
equal in magnitude but opposite in direction of the force the ball
exerts on the bat.
Is work the average force?
For a straight-line collision, the net work done is
equal to the average force of impact times the distance traveled during the impact
.
What is the reaction force of a bat hitting a baseball?
The ball exerts an equal and opposite force on the bat
. This is the reaction force. Such an interaction pair is another example of Newton’s Third Law. The baseball forces the bat in one direction and the bat forces the ball in the opposite direction.
What average force is necessary to stop a bullet of mass 20 gram?
4.
2×103N
.
What is the magnitude and direction of the impulse on the ball from the bat?
The impulse imparted to the bat is
13.3 kg. m/s
. in the direction 45-degrees towards the homeplate i.e. the same magnitude as the impulse exerted on the ball. The reason for this is that the impact force (reaction pairs) and the duration of the impact are the same for the bat and the ball and the bat.
What average force is necessary to stop a 45 caliber?
Problem Answer: The average force is necessary to stop a . 45 caliber bullet is
13.5 kN
