Question

A 25 g air hockey puck is traveling along an frictionless air hockey table at 4.0 m/s when it hits a 350 g air hockey striker, which is initially at rest. They stick together after the collision and continue along the same direction as the puck's initial path. What is the magnitude of their velocity after the collision? O 4.0 m/s O 0.29 m/s O 0.27 m/s O 14 m/s O 0 m/s

Step 1

The initial momentum of the system is equal to the momentum of the puck, since the striker is at rest. The final momentum of the system is the momentum of the combined puck and striker. Let $m_1$ be the mass of the puck and $v_1$ be its initial velocity. Let Show more…
