    Displacement is given by\[\text{x}=\text{1}+\text{2t}+\text{3}{{\text{t}}^{\text{2}}}\]. Find the value of instantaneous acceleration.

    Answer:

    Instantaneous velocity, \[\text{v}=\frac{dx}{dt}=0+\text{2}+\text{6t}=\text{2}+\text{6t}\] Instantaneous acceleration,\[\text{a}=\frac{dv}{dt}=\text{6 unit}\].
