Hannah decides to join a rodeo tour. In the first event, she is riding a bucking bronco when she is thrown off. At the instant she leaves the horse she is located 1.6m above the ground and is moving straight up at 4.0m/s. a) What maximum height above the ground does Hannah reach? b) What speed will she hit the ground? c) At what initial speed would a heavier cowgirl have to be traveling to reach the same height as Hannah in (a)? Explain

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.
