The displacement of a particle is given by ${ at }_{ 2 }$, dependency of acceleration on time? What is dependency of acceleration on time?


#2

Let x be the displacement. Then, x = ${ at }_{ 2 }$
:. Velocity of the object, v = dx/dt = -2at
Acceleration of the object,a = dv/dt = 2a
It means that a is constant.
