Question

An athlete completes 1 laps around a track with a radius of 25 meters in 180 seconds. What is the magnitude of the athlete's tangential velocity?

Answer 1

0.872m/s

Step-by-step explanation:

Tangential velocity is given by the formula,

`v= 2\pi r/ t`

In the question given,

radius= 25meters

time= 180secs

pie= 3.14

number of laps= 1

The magnitude of tangential velocity equals;

`(1lap* 2 *3.14 *25m)/(180secs)`

v = 157m/180secs

Therefore, the magnitude of the tangential velocity

=0.872m/secs
