Here, The position of the body is a function of time , i.e., x(t)= At + 4Bt³.
Now, velocity is defined as Rate of change of position of an object i.e., (position 2 - position 1 )/ (T2 - T1).
Derivative Also represents change in quantity. So in other words, *Velocity* Is Derivative of The Position of the object.
V(t) = A + 12Bt² ( using Power rule )
Power Rule- derivative of x^n = n.x^(n-1).
Acceleration is defined as *Rate of Change of Velocity*
So, the *Derivative of Velocity* gives *Acceleration*.
Therefore, acceleration here -
a(t) = 24Bt. ( Using Power rule again , Derivative of a constant is 0, therefore A is Vanished from here).
Hope this helps!
