1) A 0.45-kg ball with an initial velocity of 12 m/s, east, collides with a 0.30 kg ball initially at rest. After the collision the 0.45-kg ball has a velocity of 8.0 m/s, at 37 below its initial direction of propagation. What are the magnitude and direction of the velocity of the 0.30-kg ball after the collision? (22 points) Steiniog V'B 1 0.30 kg MB = 0.30 kg MA = 0.45 kg O O VA = 12 m/s 0.45 kg olution V'A = 8.0 m/s
