Question

In a popular amusement park ride, a rotating cylinder of radius R = 2.70 m is set in rotation at an angular speed of 4.40 rad/s, as in the figure shown below. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rider's clothing and the wall is needed to keep the rider from slipping? Hint: Recall that the magnitude of the maximum force of static friction is equal to ?sn, where n is the normal force

In a popular amusement park ride, a rotating cylinder of radius R = 2.70 m is set in rotation at an angular speed of 4.40 rad/s, as in the figure shown below. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rider's clothing and the wall is needed to keep the rider from slipping? Hint: Recall that the magnitude of the maximum force of static friction is equal to ?sn, where n is the normal force-in this case, the force causing the centripetal acceleration. ?s =

Explanation / Answer

u*n= mg

u*mv^2/r= mg
