Question

Please write out answers up to 4 significant figures. Please be thorough as the more steps the better i can understand.

Also, can you please check my force diagram for completeness and correctness? I have n for normal force, mg as downward force of mass times gravity (should i have written just g?), and Centripetal force (not sure if this is a true force).

2) A graviton ride at the fair consists of a 10 m diameter cylindrical drum that spins about its central axis at high speed, causing the riders to "stick" to the wall after the floor drops away. (a) Draw and label a force diagram for a person on the ride: complete the figure below where the person is represented by a point against the inside wall of the drum (to the left) and the center of the drum is to the right. Force Diagram & centipet (b) The ride rotates at 25 rpm. (1) What is the period of rotation in seconds? (ii) What is the speed of a rider pinned against the wall? (c) What is the minimum coefficient of static friction between the rider and the wall so that the rider does not slip down the wall?
