Two bumper cars A and B collide head-on as shown. The weights of A and B (including the drivers) are WA = 635 lb and WB = 650 lb, respectively. In addition, the preimpact speeds of A and B are  and , respectively.

Determine the COR of the impact and the postimpact speed of B if the postimpact speed of A is equal to zero.
