MCQ
The $v - t$ graph of a moving object is given in figure. The maximum acceleration is...........$\mathrm{cm/sec}^{2}$
- A$1$
- B$2$
- C$3$
- ✓$6$
✓
Answer
Correct option: D.
$6$
d
(d) Maximum acceleration means maximum change in velocity in minimum time interval.
(d) Maximum acceleration means maximum change in velocity in minimum time interval.
In time interval $t = 30$ to $t = 40\,sec $
$a = \frac{{\Delta v}}{{\Delta t}} = \frac{{80 - 20}}{{40 - 30}} = \frac{{60}}{{10}} = 6\;cm/{\sec ^2}$
