Question

A 101 Kg racer moves around a flat circular track with a radius of 55 m with a constant speed. The car makes one revolution around the track every 13 seconds. Find the speed of the car.

​

Answer 1

26.6 m/s

Step-by-step explanation:

`v = r \alpha \\ v = r( (2\pi)/(t) ) \\ v = (55)( (2\pi)/(13) ) \\ v = 26.6 \: m {s}^( - 1)`
