A particle of mass m moving with velocity u makes an elastic one dimensional collision with a stationary particle of mass m. They are in contact for a very short time T. Their force of interaction increases from zero to F_{0} linearly in time T/2, and decreases linearly to zero in further time T/2. The magnitude of F_{0} is
