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

The correct option is A 4

Acceleration, $a=\frac{\Delta V}{\Delta t}$

'a' will be maximum when this ratio is maximum,which happens for th case when velocity changes from 20-60 in 10s.

$a=\frac{40}{10}=4m/s^2$
