Question

A hockey player is initially moving at 5.00m s to the east. Her mass is 50.0 kg. She intercepts and catches on her stick a puck initially moving at 35.0m s at an angle of 30 degrees (Fig. 6.40). Assume that the puck’s mass is 0.50 kg and the two form a single object for a few seconds. (a) Determine the direction angle and speed of the puck and skater after the collision. (b) Was this collision elastic or inelastic? Prove your answer with numbers.
