A particle in motion covers half of a circular path of radius r in time t . Find the average speed and average velocity of the body.

Text Solution

Verified by Experts

The distance covered in this case = `pir`
`:.` Average speed = `(pir)/(t)`
The displacement in this case = 2r
Hence, average velocity = `(2r)/(t)`.
