The velocity-time graph for two bodies A and B are shown in figure. Then, the acceleration of A and B
are in the ratio  

The slope of velocity-time graph gives acceleration,

i.e.                   $\frac{a_A}{a_B}=\frac{\tan {\theta }_1}{\tan {\theta }_2}$

Here, ${\mathrm{\theta }}_1$ is the angle made by line A with time axis and ${\mathrm{\theta }}_2$ is the angle made by line B with time axis

$\Rightarrow$                  $\frac{a_A}{a_B}=\frac{\tan 25°}{\tan 50°}$
