67. (a) The center of mass velocity does not change in the absence of external forces. In this collision, only forces of one block on the other (both being part of the same system) are exerted, so the center of mass velocity is 3.00 m/s before and after the collision. (b) We can find the velocity v

Unformatted text preview: 1 i of block 1 before the collision (when the velocity of block 2 is known to be zero) using Eq. 9-17: ( m 1 + m 2 ) v com = m 1 v 1 i + ¡ v 1 i = 12.0 m/s . Now we use Eq. 9-68 to find v 2 f : v 2 f = 2 m 1 m 1 + m 2 v 1 i = 6.00 m/s ....
