In a classic carnival ride, patrons stand against the wall in a cylindrically shaped room. Once the room gets spinning fast enough, the floor drops from the bottom Of the room! Friction between the walls Of the room and the people on the ride make them the "stick" to the wall so they do not slide down. In one ride, the radius of the cylindrical room is R = 6.4 m and the room spins with a frequency of 21.8 revolutions per minute. Which of the following changes would decrease the coefficient of friction needed for this ride?
a. increasing the rider's mass
b. increasing the radius of the ride
c. increasing the speed of the ride
d. increasing the acceleration due to gravity (taking the ride to another planet
