A 150-m-wide river flows due east at a uniform speed of 2.0 m/s. A boat with a speed of 6.0 m/s relative to the water leaves the south bank pointed in a direction 30° west of north. (a) Draw the vectors triangle using scale 1.0 cm : 1.0 m/s and label the corresponding relative velocities. (b) Determine the magnitude of the boat's velocity relative to the ground. (c) Determine the direction of the boat's velocity relative to the ground. (d) Find the time for the boat to cross the river.
