QUESTION:
The graph in Fig. E2.31 shows the velocity of a motorcycle police officer plotted as a function of time.
(a) Find the instantaneous acceleration at t = 3 s, at t = 7 s and at t = 11 s.
(b) How far does the officer go in the first 5 s? The first 9 s? The first 13 s?
ANSWER:Step 1 of 5
According to the kinematic equation the acceleration is given by,
\(a = \frac{{\Delta v}}{{\Delta t}}\)
\( = \frac{{{v_f} - {v_i}}}{{{t_f} - {t_i}}}\,\;\;\;\;...\;\left( 1 \right) \)
Here, \({v_f}\) is the final velocity of the interval, \({v_i}\) is the initial velocity of the interval, \({t_f}\) is the final interval and \({t_i}\) is the initial interval.
