Question

a particle moving on a circular track of radius 14 m and particle moving in constant speed 11 m/s calculate the average speed and average velocity when the particle completed one and half of the revolution​

Answer 1

Answer:

A 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
