What was the speed of puck A before the collision? Express your answer in meters per second. v = 0.851 m/s Previous Answers Correct Correct answer is shown. Your answer 0.850 m/s was either rounded differently or usec IDENTIFY: Apply conservation of momentum to the system of the two pucks. SET UP: Let + be to the right. EXECUTE: PL. = P2, says (0.245 kg)v 41 (0.245 kg)(-0.119 m/s) + (0.360 k D Part B Calculate the change in the total kinetic energy of the system that occurs during the collision.

On a frictionless, horizontal air table, puck A (with mass 0.245 kg) is moving toward puck B (with mass 0.360 kg), that is initially at rest. After the collision, puck A has a velocity of 0.119 m/s to the left, and puck B has velocity 0.660 m/s to the right.
