Question

the displacement of a particle along a straight line at time t is given. the acceleration of the particle is

Answer 1

hii
as u see in the question

displacement is given

and we know displacement/time=velocity

and velocity/time=acceleration.

so we have to differentiate the displacement with respect to time two times to get the acceleration

dx/dt= a1 + 2 a2t

d2x/dt2= 2 a2

acceleration= 2 a2... answer
