Problem 2.268 A top-slewing crane is lifting an object C at a constant rate of ż = 5.3 ft/s while rotating 0.12 rad/s about the vertical axis. If the distance between the object and the axis of rotation of the crane's boom is r = 46 ft and it is being reduced %3D at a constant rate w at a constant rate of 6.5 ft/s, find the velocity and acceleration of C, assuming that the swinging motion of C can be neglected.

When a volleyball coach releases a volleyball from a height of 2 m above the gym floor, it falls to the floor and bounces back to two-thirds the same height. When it is in contact with the floor, the lower side of the ball is temporarily flattened. Suppose the maximum depth of the dent is 1 cm. (Assume the positive direction is upward.)1. Determine the acceleration of the ball (in m/s2) while it is in contact with the floor and compressing. (Indicate the direction with the sign of your answer.) 2.
