Problem: In an amusement-park ride, riders stand with their backs against the wall of a spinning vertical cylinder. The floor falls away and the riders are held up by friction. The acceleration of gravity is 9.81 m/s2. If the radius of the cylinder is 8 m,
Part A: Find the minimum number of revolutions per minute necessary when the coefficient of static friction between a rider and the wall is 0.6. Answer in units of rev/min
I need help to find the minimum number of revolutions per minute necessary.
