A block of mass m = 5.0 kg, moving on frictionless surface with a speed vi = 10 m/s, makes a sudden perfectly elastic collision with a second block of mass M which is originally at rest, as shown in the figure. Just after the collision, the 5.0 kg block recoils at a speed of 2.5 m/s. What is the momentum of the second block after collision? m before M m after M
