Question

Mr. Touhey, who's mass is 95 kg, went to the amusement park and decided to go on the "graviton" ride. he rotated without sliding (down the wall) in a circular path of radius 8 meters. the speed of the ride was then slowly decreased. the instant Mr. Tuohey's speed was decreased to 14 m/s, he started to slide down the wall. What was the frequency of the ride the instant he started to slide? What was the magnitude of his centripetal acceleration the instant he started to slide? What was the magnitude of the maximum static frictional force (available) between Mr. Tuohey and the wall the instant prior to his sliding down the wall? What was the magnitude of the normal force between his back and the wall the instant he started to slide? What was the coefficient of static friction between Mr. Toomey's back the wall?

Explanation / Answer

Centripetal accleration=v*v/r=24.5 m/s2

(IV) Normal force=m*centripetal accleration=2327.5 N

(V) let coefficient is x

Friction force=xN must balance weight so

x*Normal force=mg

x=0.4
