The velocity of a body depends on time according to the equation v = (t^2/10) + 20 . The body is undergoing -1. Uniform acceleration2. Uniform retardation3. Non-uniform acceleration

Uniform acc.

Diff. The eq. To get the relation b/w a and t!!!

But why? I don`t know you got this answar .Can you explain that, i badly need too know that why the answer is uniformly acceleration

As v=t2/10+20. So on differentiating it wrt tot we get a=t/5 so taking a as y and t as x we get a straight line equation with slope 1/5 so it is uniform acceleration . hope u get it......
