Question

The velocity-time graph of a body is given in figure. The maximum acceleration in $m{s}^{-2}$ is

• A. 4
• B. 3
• C. 2
• D. 1

Answer 1

Answer: (A)

Maximum acceleration will be from $30$ to $40s$, because slope in this interval is maximum.
$a=\frac{v_2-v_1}{t_2-t_1}$
$=\frac{60-20}{40-30}=4m{s}^{-2}$
