The displacement of a body in $8\,s$ starting from rest with an acceleration of $20\,cm / s ^2$ is $............$
A body is moving with uniform acceleration describes $40\, m$ in the first $5 \,sec$ and $65\, m$ in next $5 \,sec$. Its initial velocity will be........$m/s$
Derive the equations of uniformly accelerated motion by graphical method.
