CARFER
6.
Velocity of a body is given as a function of time as V = 15t^2+ 2t. The body is undergoing
(A) Uniform retardation
(B) Uniform motion
(C) Non-uniform acceleration
(D) Uniform acceleration​

Answer 1

differentiating the velocity to acceleration we get a=30t+2.since now i we put different values of t in 'a' we get different accelerations so it is non uniform acc.
