Please do the last three questions so 3, 4, and 5! A 20kg child is spinning on a carousel (radius =1.5m) and accelerates to a speed of 2 m/s. 1. What is the angular velocity of the carousel? The child then jumps on 2. What is the force exerted by the child if he is hanging on the bar at the edge of the carousel? 3. Now, the child moves closer inside of the carousel and is 0.5m from the center. What is the new force of the child hanging onto the bar? What is the new force if he is 0.7m from the center? 4. After 2 minutes, the carousel slowed down at about 25%. What is the total angular displacement of the carousel during the 2 minute time (in radians)? 5. Now, the child moves back out to the edge (original position) and steps off, from 8 cm above the ground? What is the speed do they hit the ground with, and in which direction?

An 8.79cm diameter floppy disk rotates at its fastest at 470 rpm. Part A: Express the angular velocity of the disk in revolutions per seconds? Part B: What is the time period of this revolution? Use scientific notation for your answer. Part C: What is the linear velocity of a point at the rim of the disk? What is the angular velocity at the center of the disk? If the disk took 3.2 sec to spin up to 470 rpm from rest, what was the average angular acceleration? How many revolutions did the disk complete within this time? What is the net displacement? If you turn off the floppy disk drive and the disk comes to a stop in 6.7 s, what is the average angular acceleration for this period of motion?
