Question

A body of mass m is moving with speed v makes a one-dimensional collision with a stationary body of same mass on a horizontal table. They are in contact for a very small time interval Δ t . The contact force between them varies as shown in the graph. (Neglect friction) The coefficient of restitution for the collision will be, 3 4, 1 2, 2 3, 1 4
