Question

The v-t graph of a moving object is given in figure. The maximum acceleration is (A) 1 cm / s 2 (B) 2 cm / s 2 (C) 3 cm / s 2 (D) 6 cm / s 2

Slope of v-t graph represents acceleration. Sir of v-t graph is maximum during time interval 30 s to 40 s. ∴ Maximum acceleration =(80-20/40-30)=(60/10) =6 cm / s 2

Q. The $v - t$ graph of a moving object is given in figure. The maximum acceleration is

$1 c m / s^{2}$

$2 c m / s^{2}$

$3 c m / s^{2}$

$6 c m / s^{2}$

Slope of $v - t$ graph represents acceleration.
Sir of $v - t$ graph is maximum during time interval $30 s$ to $40 s$ .
$∴$ Maximum acceleration
$= \frac{80 - 20}{40 - 30} = \frac{60}{10}$
$= 6 c m / s^{2}$

1cm/s2

2cm/s2

3cm/s2
