Question

the producer of the last film you worked on was so impressed with the way 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 filled 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, but the audiance dosent knoe that) you measure the diameter of the merry-go-round as 40 meters. you determine that the coeffincient of static friction between 007's shoes and the marry-go-round surface is 0.75 and the coefficient of kinetic friction is 0.6.

Explanation / Answer

Here ,

let the speed of rotation of the marry go round is w

for the person to stay on the ramp

centripetal acceleration = frictional force acceleration

w^2 *r = u*g

w^2 * 40 = 0.75 * 9.8

w = 0.43 rad/s

the angular speed of the merry go round is 0.43 rad/s
