SERPSET9 2.P.017. MY NOTES ASK The Figure Below shows a graph of v, versus t for the motion of a motorcyclist as he starts from rest and moves along the road in a straight line ", (m/s) 10 10 12 (s) (a) Find the average acceleration for the time interval t = 0 to t = 12.0 s. 1/2 X Your response differs from the correct answer by more than 10%. Double check your calculations. m/s (b) Estimate the time at which the acceleration has its greatest positive value What is the value of the acceleration at that instant? m/82 (c) When is the acceleration zero? Acceleration is zero when t s and when t > (d) Estimate the maximum negative value of the acceleration m/ At what time does it occur
