If all of the kinetic energy is conserved, the collision is completely elastic
3) The system is composed of two pool balls. The white cue
ball has a mass of 0.17 kilograms while the 8 ball has a
mass of 0.15 kilograms. The cue ball is traveling initially
at 5 meters per second. It collides with the 8 ball and
comes to a complete stop. Calculate the velocity of the 8
ball after the collision.

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.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
