A sphere of radius 10 m and a mass m1 = 5 kg is rolling without slipping on a horizotal surface with a velocity V = 20 m/s to the East. It collides with a stationery sphere of mass m2 =15 kg. After the collision both masses rolls in different directions and m1 with a velocity V = 5 m/s.
1) Find the velocity of m2 after collision
2) Find the angular velocity of m2 after the collision
3) Was the collision elastic
