Question

A circular ride has a radius of 32 m If the time of one revolution of a rider is 0.98 s what is the speed of the rider?

Answer 1

Given that,

The radius of a circular path, r = 32 m

The time of one revolution of a rider is 0.98 s.

To find,

The speed of the rider.

Solution,

Let v is the speed of the rider. Speed is equal to total distance divided by time taken.

`v=(2\pi r)/(t)\\\\v=(2\pi * 32)/(0.98)\\\\v=205.16\ m/s`

So, the speed of the rider is 205.16 m/s.
