Question

Acceleration of a particle varies with time as a =
12t2 m/s2. If the particle starts its motion from
rest, then its displacement in initial 2 seconds
will be​

Answer 1

Explanation:

Given,

u=0

t=4

Here we have to find the velocity of the particle hence we need the acceleration at t=3sec

So,

a=2+(t−2)

Substituting t=4sec

Answer 2

answer is 24m hope so

24m
