Answer:
34.78 m/s
.
What is the velocity of an object that has momentum?
In physics, momentum is a quantity that can be calculated by multiplying the mass and velocity of the object involved. Momentum is expressed by the letter p. So momentum equals mass times velocity or
p = m x v
. Therefore, if any object of any mass is not moving, its momentum is zero because its velocity is zero.
What is the velocity of an object that has a momentum of 4000?
The answer is C. You divide
4000 kg/s
by 115 kg.
What is the velocity of a skateboarder whose momentum is 100 kg?
The velocity of a skateboarder who momentum who is a 100 kg is
6.67 m/s
.
What force is required to accelerate a body with a mass of 15?
120 N
is required to accelerate a body with a mass of 15 kilograms at a rate of 8 m/s2. This answer has been confirmed as correct and helpful.
What’s the main difference between speed and velocity involves?
Speed is the time rate at which an object is moving along a path, while velocity is
the rate and direction of an object’s movement
.
What do scalars measure?
Defining Scalar and Vector Quantities
Scalar is the
measurement of a unit strictly in magnitude
. Vector is a measurement that refers to both the magnitude of the unit and the direction of the movement the unit has taken.
What is momentum in physics for kids?
Momentum is a measurement of mass in motion. Any object that is moving has momentum. In physics, momentum of an object
is equal to the mass times the velocity
.
What happens to energy when two objects collide?
When objects collide,
the energy transfers from one object to the other
. Energy is the ability to do work (or in more simple terms: energy makes things happen). The amount of energy transferred during a collision depends on the weight and speed of the moving object.
What object of small mass is high velocity?
Momentum
can be thought of as the “power” when a body is moving, meaning how much force it can have on another body. For example, a bowling ball (large mass) moving very slowly (low velocity) can have the same momentum as a baseball (small mass) that is thrown fast (high velocity).
What is the velocity of an object that has a momentum of 4000 kg/m s and a mass of 115 kg round to the nearest hundred?
The answer is C. You
divide 4000 kg/s by 115 kg
.
What is the velocity of a skateboard?
Overall average skateboard speed is
around 9 mph
including all types of skills, terrain, and setups. Typical skateboard speed falls in the 5 – 12 mph range. Experienced skateboarders frequently commute at average speeds of 7 – 8 mph on 1-2 miles flat trips.
What is the acceleration of the book Weegy?
The acceleration of the book is
40 m/s
.
What is the force of gravity on a 20kg object?
If an object has a mass of 20 kg, The force of gravity acting on earth is
196N
.
What force in Newtons is required to accelerate a body?
Force required to accelerate the body is
6N
.
Why do we measure force?
Forces cause things around you to move
. Force is measured in Newtons, which are units that equal 1 kg * m/sec2. You can calculate the amount of force that an object experiences with the equation force = mass * acceleration. If you know any two of these values, you can use them to find the third.
