Question: 4. A student is rolling down a hill while stuffed into a very large tire with a radius of 1.5m. The frequency of rotation reached

4. A student is rolling down a hill while stuffed into a very large tire with a radius of 1.5m. The frequency of rotation reached by the tire is 1.2 hertz. Draw a diagram to support your solution.

  1. Find the speed of rolling tire
  2. Find the centripetal acceleration acting on the student? How many g's do they feel at top and bottom of their motion?
  3. If at the bottom of the hill, the tire "de-accelerates" at a rate of 10m/s2 {backwards}, how long does it take for student to "fall" out of tire well due to it's slow rotation?
