2. a force of 156 n acts on a 7.3-kg bowling ball for 0.40 s.
a. what is the bowling ball's change in momentum?

Explanation:

The change in momentum of the ball is equal to the impulse exerted on it, therefore:

where

is the change in momentum

F is the average force exerted on the ball

is the time during which the force is applied

In this problem,

F = 156 N

So, the change in momentum of the ball is

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
