A 5 kg cart moving at 10 m/s collides inelastically with a 3 kg cart at rest. Calculate the final velocity after the collision.
💡 Hint: Remember to conserve momentum through the whole system during the collision.
Two ice hockey pucks collide on a frictionless rink. Puck A (0.5 kg, moving at 2 m/s) collides elastically with puck B (0.3 kg, at rest). What are their velocities after collision?
💡 Hint: Use both conservation of momentum and kinetic energy formulas to solve.
