Mass 1 has a momentum of 20 kg*m/s. Mass 2 has a momentum of 50 kg*m/s. They have a perfectly elastic collision. After the collision, the momentum of Mass
1 is 15 kg*m/s. What is the momentum of Mass 2?

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.
