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

16 m

24 m

64 m

4 m m​

Answer 1

Answer:

16 meteres

Explanation:

You just have to integrate acceleration twice to get the equation for displacement as a function of time.. And the put the value of t in the equation.

a=12t^2

v=4t^3

s=t^4

where t is 2 sec.

hence displacement is 16 m

Answer 2

answer- 16m
