tittle projectiles summative assessment projectile motion and motion in 2d Name: Breonna Bailey Date: NON 1. You're a criminal investigator and need evidence to discover the mystery of a crash. a car traveled the distance of 73m before smashing into the ground it ran off a cliff .the cliff is 32m high from the base to the top . the road was horizontal when the car left the edge of the cliff . what was the initial velocity of the car before it left the edge of the cliff ?

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.
