In Figure block A (mass 1.6 kg) slides into block B (mass 2.4 kg), along a frictionless surface. The directions of three velocities before (i) and after (f) the collision are indicated; the corresponding speeds are vAi = 5.5 m/s, vBi =2.5 m/s, and vBf = 4.9 m/s. What are the

(a) Speed and

(b) Direction (left or right) of velocity vAf?

(c) Is the collisionelastic?
