The first collision (conservation of energy, momentum) gives you the speeds of M1 and m2 after the collision. Then, the distance m2 travels is 70 cm + (70-x) cm. But it does it in the same time as m1 travel x cm. You have the distances, velocitys, and times, solve for x.

ok so velocity of m1 = 150 m/s and m2 = -29 m/s.....where do i go from there?
