Question

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

Answer 1

The correct option is C Non-uniform acceleration

Acceleration $a=\frac{dv}{dt}=0.1\times 2t=0.2t$
Which is time dependent i.e. non - uniform acceleration
