Q. A bungee jumper with mass 63 jumps from a high bridge. After reaching his lowest point, he oscillates up and down, hitting a low point eight more times in 47. He finally comes to rest 21.00 below the level of the bridge.
Q. A ceiling fan with 86.00 diameter blades is turning at 65. Suppose the fan coasts to a stop 26 after being turned off. What is the speed of the tip of a blade 10 after the fan is turned off?
