Challenge Problems
Push your limits with challenges.
Question 1
A 5 kg ball moving at 10 m/s collides elastically with a 3 kg ball at rest. What is their final velocity after the collision?
💡 Hint: Set up two equations: one for momentum and one for kinetic energy.
Question 2
In a perfectly inelastic collision, a 2 kg object moving at 12 m/s collides with a 3 kg object at rest. What is their joint velocity after collision?
💡 Hint: Use the formula for conservation of momentum.
