A fairground ride spins its occupants inside a flying saucer-shaped container. If the horizontal circular path the riders follow has a 9.3 m radius, if the riders is subjected to a centripetal acceleration 3.1 times that due to gravity, what is the spinning speed in unit of revolutions per minute?

Fitness is the ability to perform only very light levels of physical activity.

Scientific classification

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
