Question

two aircraft P and Q are flying at the same speed 300 ms^-1 the direction along which p is flying is at right angle to the direction along which Q is flying
A)find the magnitude of the velocity of the aircraft P relative to aircraft QQ
B) find the direction of the velocity

Answer 1

A)

$$v=\sqrt{300^2+300^2}=424\frac{m}{s}$$

B) The direction of the velocity is $45\degree$ to the direction along which Q is flying and P is flying.
