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, 1
1, 1
1, 0.5
0, 2
As discussed in concept
Coffecient of Restitution (e) -
- wherein
Ratio of relative velocity after collision to relative velocity before collision.
- (i)
