a point Pmoves along the axis so that its positon x at time t is given by x=t^3-4t+1.

a point Pmoves along the axis so that its positon x at time t is given by x=t^3-4t+1.a) find the velocity and accleration of P at time tb)determine the following the time interval on which the point is moving to the rightthe time interval on which the point is moving to the leftthe acceleration at the times when the velocity is zerothe average velocity over the time interval [0,4]
