Practicing Success
A ball moving with velocity 2 m/s collides head on with another stationary ball of double the mass. If the coefficient of restitution is 0.5 then their velocities (in m/s) after collision will be |
0, 2 0, 1 1, 1 1, 0.5 |
0, 1 |
m x 2 = m x v1 + 2mv2 2 = v1 + 2v2 0.5 x 2 = v2 - v1 v2 = 1, v1 = 0 |
