Question

A particle moving along the square path ABCD with constant speed 'V'. Find Average Speed and Average Velocity when particle completes A to C.

Answer 1

$$\begin{gathered} \mathrm{Average}\mathrm{speed}=\mathrm{Constant}\mathrm{speed}=\mathrm{v} \\ \mathrm{Average}\mathrm{velocity},\mathrm{v}\text{'}=\sqrt{{\mathrm{v}}^2+{\mathrm{v}}^2}=\mathrm{v}\sqrt{2} \end{gathered}$$
