What is an elastic collision?

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies is different.

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.

What is an inelastic collision?

When two objects collide, becoming stuck together and internal kinetic energy is lost (but not really lost, it transfers to different forms of energy)

When two objects collide, becoming stuck together and internal kinetic energy is lost

When two objects don't collide, becoming stuck together and internal kinetic energy is lost (but not really lost, it transfers to different forms of energy)

Mr. Haggerty and Mr. Greenwalt have dressed up in sumo wrestling costumes. They form a perfectly elastic collision. Mr. H has a mass of 56 kgs and a velocity of 6 m/s. Mr. G has a mass of 43 kgs. After they collide Mr. H has a velocity of -2 m/s and Mr. G has a velocity of 8 m/s. What was Mr. G's initial velocity? Round to the nearest one decimal place. Don't write units
