Question
Here's a YouTube video of another version of the Wall of Death ride (remember the Simpson's Movie?): http://www.youtube.com/watch?v=dNiYDo3vH9cLet's assume the car/person had a mass of 140 kg and the diameter of the circle was 4 meters.
(a) What was the period of the car once it had reached a steady speed & position on the wall?
(b) What was the car's tangential speed?
(c) What was the car's inwards (centripetal) acceleration?
(d) What was the normal force on the car from the wall?
(e) What was the average friction force on the car from the wall?
Explanation / Answer
The period is 2s....the time it takes for the bike to go around once tanginal speed is equal to V = 2(pi)r/T diameter is 4 meters so radius is 2 m solve to 6.3 m/s acceleration is equal to a=v^2/r a =19.7
