Question

A particle moving along the circumference of a circle of radius 1m completes 3/4 of a circle in 10second.what is the average velocity of the particle?

Answer 1

Answer:

particle moving along a circular path of radius 6m uniform speed of 8ms

−1

.

the particle has velocity tangential to the circle all the time when particle complete half the circle than its change its direction opposite to each other.

initial and final velocity is v
