(1) A sailboat is sailing at a bearing of 35° North of East, while the wind is exerting a force of 750 Newtons to the Northon the sails. How much work does the wind do while the sailboat travels 4 kilometers? Hint: draw the vectors andnote that Ois the angle between the vectors when you put their tails together.For three dimensional vectors Ä = A,î + Ayj + A,k and B = B,î + Byj + B,k , the scalar product written in terms ofcomponents will be A ·B = A,Bx + AyBy + A,Bz. This gives us two ways to calculate the scalar product (i) using themagnitude of the vectors and the angle between the vectors and (ii) using the components of the vectors. We choosewhichever method is easier for the particular problem.
