Circular Motion

Question

A hamster runs at a constant speed on a wheel.

The radius of the wheel is 10.8 centimeters.

As the hamster runs, the wheel turns 9 complete times every 0.54 seconds.

Answer 1

pi*2*10.8 = 67.858401317539533950793097078837 cm is one revolution

Multiplying by 9, 610.72561185785580555713787370954 cm every 0.54 seconds

9 revolutions per second = 610.72561185785580555713787370954 cm every 0.54 seconds

1131 cm per second
