Question

a cyclist goes around a circular track once every 2 minutes if the radius of the circular track is 110 M calculate the speed of the cyclist

Answer 1

it is completing one revolution in 120 second

therefore distance travelled in 120 second = 2$\pi$ r

where r is the radius of the circle

terefore speed = distance travelled / total time taken

= 2$\pi$r/120

=17.28m/s

hence the speed is 17.28m/s

Answer 2

Answer:

Explanation:

First we convert 2 minutes into seconds 2 into 60 is equals to 120 seconds now velocity is equals to2 ×22×110÷7×120
