a) Define uniform acceleration. What is the acceleration of the body movingwith uniform velocity?b) A particle moves over three quarters of a circle of radius r. What is themagnitude of its displacement?
If a body is moving with uniform velocity then there is no change in the velocity of the body and hence, the acceleration will be ZERO.
(B) When a particle moves over three quarter of the circle then its displacement is given as under:
The body starts moving from point A and reaches point B. Then the displacement is 'd'
