We got the following:
m = 78kg
h = 6m
g = 9.8 m/
≈ 10 m/
----------------------------------------------------------------------------
A = ?
As we know A = Ep = mgh -> potential energy
so the answer would be A = 78 * 6 * 10 = 4680 Joule
Answer:
p = mv
Explanation:
- The momentum of a body is defined as the product of its mass and velocity. Its physical symbol is 'p'.
- The formula for momentum is given by
p = mv
Where,
m - the mass of the body in kg
v - velocity of the body in m/s
- Therefore, the unit of momentum is expressed as the kg m/s
- The momentum of a body is always associated with its motion. It is a vector quantity and it is directed in the direction of the velocity vector.
- If a body is at rest, the momentum associated with the body is zero.
- The momentum plays a significant role in the kinematics of the body. As similar to the energy conservation law, the total momentum of the body is conserved.
