A ball falls off a building which has a height of 100 meters. It hits the ground 4 seconds later. What is the displacement of the ball? *

100 meters

Explanation:

the displacement is the distance from which it started, so if it falls 100 meters, then it has a 100 meter displacement

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.
