CHECKPOINTS (continued) 10. A billiard ball collides with an identical stationary billiard ball. Assuming that the
collision is elastic, which of the following is true of the ball that was originally
stationary?
O a. It moves in the opposite direction as the ball that collided with it, and it has
half the velocity.
Ob. It moves in the same direction and with the same velocity as the ball that
collided with it.
O c. It remains stationary.

Industrial processes often require the damping of vibrations. consider a workbench that uses four large ideal springs in place of traditional legs, with each spring supporting one corner of the workbench and exhibiting a force constant of 47500 n/m. this workbench is used when creating products that involve highly unstable chemicals. according to specifications, the acceleration of the manufacturing equipment must be held to less than 22.3 m/s2 for the manufacturing process to proceed safely. the amplitude of vibrations are expected to remain under 0.622 mm throughout. given that the workbench and maufacturing equipment combine to 6.05 kg, find the maximum acceleration expected of the equipment and workbench. (ignore the mass of the springs.)
