Challenge Problems
Push your limits with challenges.
Question 1
Mass m1 (3 kg) traveling 5 m/s collides with stationary mass m2 (5 kg). If the collision is perfectly elastic, find the final velocities of both masses.
💡 Hint: Set up the equations from both conservation principles.
Question 2
In a two-dimensional collision, mass m1 (2 kg) moving at 4 m/s collides elastically with mass m2 (2 kg) at rest at an angle of 30 degrees. Calculate the velocities after the collision.
💡 Hint: Use components and conservation laws effectively for the right application.
