A straight river flows east at a speed of 20mi/h. A boater starts at the south shore of the river and heads in the direction which is 60o to the south shore. The motorboat has a speed 20 mi/h relative to the water. (a) Express the velocity of the river as a vector in component form; (b) Express the velocity of the motorboat relative to the water as a vector in component form; (c) Find the true velocity of the motorboat; (d) Find the true speed of the motorboat; (e) Find the true direction of the motorboat (the bearing).
