A puck of mass 0.70 kg approaches a second, identical puck that is stationary on frictionless ice. The initial speed of the moving puck is 5.0 m/s. After the collision, one puck leaves with a speed vi at 30° to the original line of motion. The second puck leaves with speed v2 at 60°. (a) Calculate V1 and v2. Vi = 866025 x Vy = 250011 x m/s m/s (b) Was the collision elastic? Yes No eBook
