2atest pilot wcighing 85 kg is strapped into a large centrifuge machine for training the machine
spins rapidly to simulare increased gravitational forces on the body
a the machine spins the pilot in a cirde with a 9.9 m radius, what should be the period of
folation so that the pilot experiences a force equal to twice his body weight? what should be
the period of rotation so that the pilot experiences a force equal to three times his body
weight
b. astationary observer watches as the pilot spins in the machine. from the frame of reference of
the stationary observer, how fast is the pilot traveling as he passes by while experiencing a force
three times that of gravity? give your answer in revolutions per minute, ipm
c. if the radius of the cirde increases but the pilot continues to spin at the same speed, does the
pilot experience more or less force? what can be done to maintain the same force on the pilot?
