Show all the steps and details and also draw a diagram of the problem

The producer of the last film you worked on was so impressed with the w ay you handled a helicopter scene that she hired you again as technical advisor for a new spy film. The scene calls for the spy to chase a villain onto a merry-go-round An accomplice starts the merry-go-round rotating in an effort to toss the spy off into an adjacent pool tilled with hungry sharks. You must determine a safe rate of rotation such that the stunt man will not fly off the merry-go-round and into the shark-infested pool. (Actually they are mechanical sharks, hut the audience doesnt know that.) You measure the diameter of the merry-go-round as 40 meters You determine that the coefficient of static friction between 007s shoes and the merry-go-round surface is 0.75 and the coefficient of kinetic friction is 0.6. your answer must be organized, clear, and include the elements of the problem solving path: Focus the Problem Describe the Physics Plan the Solution Execute and Evaluate

Explanation / Answer

Here ,

1) the problem is for the person to stay on the platform woth slipping

2)

for the problem ,

for the person to stay at the place , there should be centripetal force acting on the person , and the frictional force will provide this centripetal force .

3)

frictional force = us * normal force

centripetal force = m*w^2 * r

4)

m*w^2 * r = us * m * g

w^2 * 40 = 0.75 * 9.8

w = 0.429 rad/s

the angular velocity is 0.429 rad/s
