# two particles move simultaneously from two points A and B, 300m apart, the particle at A starts towards,B with a velocity of 25m/s & that at B,moves normal to the former with a velocity of 20m/s . find the relative velocity of the particle at A w.r.t to that at B . Determine whenr they closest to each other

Dear student

If the velocities of particles A and B are $\mathbf{v}_A$ and $\mathbf{v}_B$ respectively in terms of a given coordinate system, then the relative velocity of A with respect to B (also called the velocity of A relative to B, $\mathbf{v}_{A/B}$, or $\mathbf{v}_{A \mathrm{\ rel\ } B}$) is

$\mathbf{v}_{A \mathrm{\ rel\ } B} = \mathbf{v}_A - \mathbf{v}_B$.

Conversely, the velocity of B relative to A is

$\mathbf{v}_{B \mathrm{\ rel\ } A} = \mathbf{v}_B - \mathbf{v}_A$.
