A student drops a 6.8 kg bowling ball onto a trampoline and allows the bowling ball to bounce one time. The graph shows the vertical velocity of the bowling ball as a function of time, where upward velocity is considered positive. (a) How can this graph be used to determine the acceleration of gravity?
For parts (b) and (c), full credit will be awarded only to responses that show equations, calculations, and verbal explanations for how quantities were found from the data.
(b) What is the ball’s change in momentum as a result of being in contact with the trampoline?
(c) What average force is applied to the ball while it is in contact with the trampoline?

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.
