A 0.180-kg round puck is placed inside a horizontal spring-loaded on a frictionless surface. The spring is released and the puck leaves the launcher with 2.50 J of kinetic energy, and slides across the frictionless surface until it strikes a 0.300-kg square block at rest on the surface. Before After 1'nob uoverli Aoiailloo srh 19fhs dado vibolovri el o noieilloo m1 = 0.180 kg m2 0.300 kg 1. What was the puck's velocity just before striking the block? 2. What was the puck's momentum just before striking the block? Scone 3. After striking the block, the puck bounces backwards with a velocity of -1.10 m/s. What is its momentum after this collision? Don't forget about the sign. (You don't know if the collision is elastic.)
