1. Two large balls roll over a smooth surface and collide. They are made of a super hard material so there is no deformation. Ball 1 has a mass m of 2.00 kg and travels with an initial velocity of 10.0 m/s. Ball 2 has a mass m2 of 5.00 kg and travels with an initial velocity of 1.42 m/s. A diagram of their collision is shown below. After the collision, what is the velocity of (a) ball 1 and (b) ball 2? m1 20 Vi 10 m1 60 7 M2 Vzi m2
