If a rock of mass 1 kilogram is thrown straight upward with an initial speed of 40 m/s, how high above the point it is released will it go? select one: a. 40 m b. 80 m c. 20 m d. 50 m

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.
