A NASA centrifuge spins astronauts around in a compartment attached to a long arm. A diagram of the centrifuge is shown below.

c. If the arm has a radius of 7.1 m and spins the astronaut with a speed of 13.5 m/s, what is the acceleration of the astronaut? (1 point)
d. The maximum acceleration the centrifuge can produce is 14.5 g. What is this acceleration in m/s2? (2 points)
e. How fast would the compartment have to move to produce an acceleration of 14.5 g? (1 point)
