Challenge Problems
Push your limits with advanced challenges
A 2 kg cart moving at 3 m/s collides with a stationary 4 kg cart. Assuming a perfectly elastic collision, calculate the final velocities of both carts.
💡 Hint: Apply conservation of momentum and elastic collision formulas.
If a 5 kg object moving at 10 m/s collides with a 3 kg object at rest and they stick together, find their shared velocity after the collision.
💡 Hint: Use p_initial = p_final and consider both objects as a single unit post-collision.
