Solutions

Expert Solution

The displacement function is given by

, by Applying the initial condition s(0)=4, we will get s(t).

The displacement travelled between the time t=2 and t=4 is given by, s=s(4)-s(2) and the distance travelled between t=2 and t=4 is given by d=||s(4)|-|s(2)||. The particle moves forward if the velocity is positive and backward when velocity is negative.

The acceleration function is defined as the rate of change in velocity, i.e, a(t)=v'(t).
