I need the ans with relevant figure : Two particles P and Q, are
30m apart with Q due north of P. Particle Q is moving at 5m/s in
a direction 90 deg and P is moving at 7m/s in a direction 30
deg. Find (a) the magnitude and direction of the velocity Of Q
relative to P, (b) the time taken for Q to be due east of P,to
the nearest second.
