1. Apply the laws of conservation of momentum and kinetic energy.
2. Write down the equations for elastic collisions (v1f = (m1 - m2) / (m1 + m2) * v1i + ...).
3. Solve the equations to find the final velocities.

v = √(20² - 2(9.8)(15)) = √(400 - 294) = √106 ≈ 10.3 m/s These links provide thousands of past problems from
