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 m24 m64 m4 m m​

Answer»

16 meteresExplanation: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^4where t is 2 sec. HENCE displacement is 16 m
