During a hurricane, a large tree limb, with the mass of 23.0 kg at a height of 15.3 m above the ground, falls on a roof that is%5.00 m above the ground. Ignoring air resistance, a. what is the kinetic energy of the limb when it reaches the roof?

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.
