Question

When a body accelerates by αt, what is the velocity after time ‘t’, when it starts from rest?​

Answer 1

In the question the time dependence of acceleration has been givn as , a = αt. So, it is the velocity after time 't'.

Answer 2

Answer:

at^2

Explanation:

Given,

u=0 (starts from rest)

a= at

t=t

v=?

According to the first kinetic equation,

v=u+at

v=0+at(t)

v=at^2
