Question

Hello. You are on an amusement park ride with your backagainst the wall of a spinning vertical cylinder. The floor fallsaway and you are held up by static friction. Assume your mass is65 kg. My values for this question areradius of 4m and coefficient of static friction of .41. I amhaving trouble with part c which asks for the minimum period tokeep the person from sliding down. I have calculated thecorrect answer for the force of friction as 637N. From that Icalculated the normal force as 1533.66N. In the x direction Ihave the normal force = ma. I found the acceleration fromthere to be 23.9m/s^2. Then I used a=v^2/r to find thevelocity (9.778m/s). I then used that velocity in 2*pi*r/v tocome up with 2.57s. That answer is coming up wrong. Thank you for your time.

Explanation / Answer

In this case, the revolutions permin would be calculated by : {9.778m/s(60sec/min)} /2(4) ˜ 23.34 rpm {9.778m/s(60sec/min)} /2(4) ˜ 23.34 rpm
