A boat is travelling at an angle of a=60° east of North at a constant speed u=3.0ms-1. A man is swimming at a constant speed v in order to reach

the boat from a point a distance /=100m due east of the boat. a) Find the direction in which the swimmer should head in order to reach theboat with the minimum speed. b) Show that the minimum value of v if the swimmer is to reach the boat is1.5 ms-1. c) How long will it take if swimming at 1.5 ms-1?
