Chapter 9, Problem 60(choose chapter or problem)
In Fig. 9-64, 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 v Ai = 5.5 mis, VBi = 2.5 mis, and VB! = 4.9 m/s. What are the ( a) speed and (b) direction (left or right) of velocity VA/ (c) Is the collision elastic?
