Question

Two aircraft p and q are flying at the same speed ,300m s^-1, the direction along which p is flying is at right angle to the direction along which q is flying .find the magnitude of the velocity of aircraft p relative to aircraft q.,,,,,,(hellllp if poassible lead to to graph too I have 5 hours to school to submit it
P.s ( are they goin the same direction or opposite I didn't get the right angle to q

Answer 1

Two aircraft p and q are flying at the same speed, $300\mathrm{m}\ \mathrm{s}^{-1}$, the direction along which p is flying is at right angle to the direction along which q is flying. Find the magnitude of the velocity of aircraft p relative to aircraft q

P.s ( are they going in the same direction or opposite I didn't get the right angle to q

Solution

the velocity of aircraft p relative to aircraft q $\overline{V_p - V_q} = \overline{V_p} - \overline{V_q}$ its magnitude

$$\begin{array}{l} \left| \overline{V_p - V_q} \right| = \sqrt{V_p^2 + V_q^2 - 2 V_p V_q \cos a} = \\ \sqrt{300^2 + 300^2 - 2 \cdot 300 \cdot 300 \cdot \cos 90} = 424\ \mathrm{m/s} \end{array}$$

P.s. (they are perpendicular to each other)
