B) Body A of mass 3 kg is moving in the +x-direction with a speed of 15 m/s. Body B of mass 5 kg is moving in the -y-direction with a speed of 7 m/s. What are the x- and y-components of the velocity of the center of mass of the two bodies?
vcmx= _____ m/s
C.) Two identical pucks are on an air table. Puck A has an initial velocity of 3.7 m/s in the positive x-direction. Puck B is at rest. Puck A collides elastically with puck B and A moves off at 1.5 m/s at an angle of +60° above the x-axis. What is the speed and direction of puck B after the collision? (Let angles above the +x-axis to be positive and below to be negative.)
