Problem 14.7

Please wait for the animation to completely load.

A block of wood floats in a bucket of water.  The bucket is placed in an elevator as shown in the animation (position is in meters and time is in seconds).  Restart.

1. Elevator in free-fall:  If the picture on the left represents the orientation of the wood when the elevator is stationary, which animation correctly depicts the new orientation of the wood while the elevator is in free-fall as shown (assume a broken cable)?

2. Elevator rising:  If the picture on the left represents the orientation of the wood when the elevator is stationary, which animation correctly depicts the new orientation of the wood while the elevator is moving as shown.
