A body is moving with a uniform velocity of 20 m/s in a particular direction. The velocity of this body along a line 60° w.r.t this direction is. ————

Answer 1

$$\begin{gathered} \mathrm{Component}\mathrm{of}\mathrm{velocity}: \\ \mathrm{v}\text{'}=\mathrm{vcos\theta } \\ =20\times \cos {60}^{\mathrm{o}} \\ =20\times \frac{1}{2} \\ =\mathbf{10}\mathbf{}\mathbf{m}\mathbf{/}\mathbf{s} \end{gathered}$$
