Some informations are given for a body moving in a straight line. The body starts its motion from rest at `t=0`.
Information I : The velocity of a body at the end of `4s` is `16 m//s`
Information II : The velocity of a body at the end of `12s` is `48 m//s`
Information III : the velocity of a body at the end of `22s` is `88 m//s`
The body is certainly moving with

Options

A. Uniform velocity
B. Uniform speed
C. Uniform acceleration
D. Data insufficient for generalization

Answer

D

Explanation

Here average acceleration `=(16-0)/(4-1)=(48-16)/(12-4)=(88-48)/(22-12)=4`
But we can't certainly that body have uniform acceleration.
