A small box of mass m slides on frictionless ice with initial speed v to the right. It approaches a large box of mass 2m which is initially at rest. The boxes collide and do not stick together. After the collision, the small box m is motionless. What is the speed of the large box, 2m, after the collision? Before collision After collision m 2m 2m O 0.71v V O 1.41v 0.5v 2v
