What is the momentum of a body of mass 2Kg at its highest point?
Mass=2Kg. velocity=5m/s. So Momentum=2×5=
10Kgm/s
.
What is the momentum of highest point when a body is thrown upwards?
The
momentum is zero
. Explanation: momentum is the product of mass and velocity of a particular material . And when ball is thrown vertically upwards its velocity at highest point is zero .
What is the momentum of a body of 2 kg at its highest point when thrown with a velocity of 15 m/s at an angle of of 70o with the horizontal?
What is the momentum of a body of 2 kg at its highest point, when thrown with a velocity of 15 m/s at an angle of of 70
o
with the horizontal?
9.23 kg ms
.
What is the highest point of motion?
The highest point in any trajectory, called
the apex
, is reached when v
y
= 0. Since we know the initial and final velocities, as well as the initial position, we use the following equation to find y: v2y=v20y−2g(y−y0).
What would be the momentum at the highest point of its flight?
As on highest point velocity is
zero
. Hence momentum will also be zero as it is the product of mass and velocity of a body.
Can momentum be created?
The conservation of momentum states that, within some problem domain, the amount of momentum remains constant;
momentum is neither created nor destroyed
, but only changed through the action of forces as described by Newton’s laws of motion.
What is momentum unit?
Momentum can be defined as “mass in motion.” All objects have mass; so if an object is moving, then it has momentum – it has its mass in motion. … The units for momentum would be mass units times velocity units. The standard metric unit of momentum is
the kg•m/s.
Which of the following is unit of momentum?
| Momentum | Common symbols p, p | SI unit kilogram meter per second kg⋅m/s | Other units slug⋅ft/s | Conserved? Yes |

What is the value of gravitation potential energy of the body of mass 2 kg which is projected vertically upwards with a speed of 3 m s?
g =
9.8 m/s2
How is projectile motion used in real life?
In real life, the projectile motion
finds applications in sports
. Playing basketball, football is examples of projectile motion in real life. While throwing a basketball into the basket, the player shoots the ball in such a way that the flight taken by the ball is in the form of a parabola.
Why is velocity 0 at maximum height?
Answer: 0 m/s.
The instantaneous speed of any projectile at its maximum height is zero
. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.
How do you determine the highest point?
- if α = 90°, then the formula simplifies to: hmax = h + V02 / (2 * g) and the time of flight is the longest. …
- if α = 45°, then the equation may be written as: …
- if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that’s the case of horizontal projectile motion.
Is there momentum in space?
Momentum is defined as the mass of an object times its velocity. … In a similar manner, a rocket moves in space because the gases are given momentum as they are expelled by the rocket engine. Consider the rocket resting in space.
There is no momentum in the system
.
How do you find initial momentum?
The Momentum Calculator uses the formula
p=mv
, or momentum (p) is equal to mass (m) times velocity (v). The calculator can use any two of the values to calculate the third.
What will be the initial momentum?
Initial momentum refers to the momentum of an object
when it first starts moving
.
