The green block(B) has a mass of 10.00kg and is moving to the left at a speed of 3.70m/s. The red block(A) has a mass of 7.10kg and is moving to the right. The two blocks undergo a perfectly inelastic collision. What should the velocity of the red block be in order to have the two blocks move to the right with a speed of 1.30 after the collision?
