A body travels along a circular path of radius 70 m. After travelling half a revolution in 20 s, What would the average velocity of the body be?

A body travels along a circular path of radius

70 m

. After travelling half a revolution after

20 \sec

7 m / s

.
The body completes half of a revolution of the circular path of radius

(r)

70 m

20 \sec

.
Total displacement covered by the body

s = 2 r

= > s = 2 \times 70

= > s = 140 m

We know that

average velocityAverage velocity = \frac{total displacement}{total time}

= > v = \frac{140}{20}

= > v = 7 m / s

A body travels along a circular path of radius $70 m$ . After travelling half a revolution in $20 s$ , What would the average velocity of the body be?
