# 17. Figure P2.17 shows a graph of v, versus t for the motionof a motorcyclist as he starts from rest and moves alongthe road in a straight line. (a) Find the average acceleration for the time interval0 to t- 6.00 s. (b) Esti-mate the time at which the acceleration has its greatestpositive value and the value of the acceleration at thatinstant. (c) When is the acceleration zero? (d) Estimatethe maximum negative value of the acceleration andthe time at which it occurs.V^ (m/s)1064461012Figure P2.17

Step 1

(a)

The expression for the average acceleration for the time interval t=0 to t=6s,

Step 2

Substitute the values,

Step 3

(b)

The greatest acceleration will occur at that point where the slope has maximum value. SO, the maximum s...
