The velocity of body is given as `v = 20 + 0.1 t^2`. The body is undergoing

Options

A. uniform acceleration
B. uniform retardation
C. non-uniform acceleration
D. zero acceleration

Answer

C

Explanation

`v=20+0.1 t^(2)`
`a=(dv)/(dt)=0.1xx2t=0.2t`
as acceleration depends on time and it is increaesing with time, hence it is non uniform acceleration.
