A 50 KG ice skater on ice moving at 2.5 m/s collides gently with a second 60 KG ice skater initially at rest and they continue to move as one body in the same direction. A) what is the speed after the collision? B) calculate the force eat skater feels during this gentle collision, lasting 0.5 seconds. C) calculate the total kinetic energy before and after the collision. Are they equal? If not, what percent of the energy was lost during the collision? Is this collision elastic or inelastic?
