I found the centripetal acceleration to be 45.4 m/s^2 a=(4π^2(r))/T^2. The equation I have for centripetal force is F=mass*centripetal acceleration, but my problem is the problem didn't give a mass for a human so that's where I'm stuck at. I know that some problems we did in class the masses...
In a "Rotor-ride" at a carnival, people are rotated in a cylindrically walled room (think of a ride like the gravitron). The room radius is 4.6m and the rotation frequency is .4 revolutions per second when the floor drops out. What is the minimum coefficient of static friction so that the...
