Q. The velocity of a body depends on time according to the equation $v = 20 + 0.1t^{2}.$ The body is undergoing
A) Uniform acceleration
B) Uniform retardation
C) Non-uniform acceleration
D) Zero acceleration
Explanation
(c) $Acceleration = a = \frac{dv}{dt} = 0.1\ \times 2t = 0.2t$
Which is time dependent $i.e.$ non-uniform acceleration
