A particle of mass m moving with a velocity u makes an elastic one-dimensional collision with a stationary particle of mass m establishing a contact with it for extremely small time. T. Their force of contact increases from zero to F0 linearly in time T/4, remains constant for a further time T/2 and decreases linearly from F0 to zero in further time T/4 as shown. The magnitude possessed by F0 is.
