A boat start sailing on Monday 10:00 at harbour A and sails 600km due north. Later it turns east for a further 420km to reach harbour B on Tuesday at 12:00.a)find total displacement from A-B average. b)speed of the trip.c)average velocity
use the Pythagorean Theorem to get the final displacement
the speed is the (actual distance covered)/(total time)
the average velocity is the displacement/time, with its direction.
Draw a diagram to get the direction of the bearing of B from A.
