Question

A hamster runs in its wheel whose radius is 3 inches. The wheel completes 7.3 revolutions in 6 seconds.


What is the linear velocity of the hamster's wheel?

Answer 1

Answer: Linear speed is 22.6 in/sec
Explanation: 1.2•18.8= 22.6
I got those numbers by dividing 7.3 in 6 and got the 1.2 rev/sec.
Radius= 2pi ( 3in)= 18.8
