Question

05. The time required to complete one lap around a perfectly circular track having a radius of 1,835 meters is 86

seconds. What is the car's velocity?
please help!

Answer 1

v = 134.06 m/s

Step-by-step explanation:

Given that,

Radius of a circular track is 1,835 m

Time required to complete one lap around a perfectly circular track is 86 seconds

We need to find the car's velocity. Velocity is equal to,

v=d/t

On circular path,

`v=(2\pi r)/(t)\\\\v=(2\pi * 1835)/(86)\\\\v=134.06\ m/s`

So, car's velocity is 134.06 m/s.
