1.	Graph of velocity (v) versus time 't' for motion of a motorbike which starts from rest and moves along a stright road is given . (a) Find the average acceleration for the time interval t_(0)=0 to t_(1)=6.0s(b)Estimate the time at which the acceleration has its greatest positive value and the value of the acceleration at the instant. (c) When is the acceleration is zero? (d) Estimate the maximum negative value of the acceleration and the time at which it occurs.
