Challenge Problems
Push your limits with challenges.
Question 1
Two carts collide elastically. Cart A has a mass of 2 kg and is moving at 4 m/s toward Cart B, which has a mass of 3 kg and is at rest. Calculate their final velocities after the collision.
💡 Hint: Set up the equations based on known quantities.
Question 2
A 5 kg ball moving at 20 m/s collides with a 10 kg ball at rest. If the collision is completely inelastic, find the final speed and the kinetic energy lost.
💡 Hint: Apply the formulas you've learned for both parts.
