2. Olaf swims at a speed of 1.55 m/s relative to the water. He swims across a 64 m wide river in 44 seconds at an angle such that he ends up directly across from his starting point as shown in the diagram below. (5 pts A) end 64 m start a. Sketch the overall vectors of the person to the water, the water to the ground and the person to the ground. Write the equation for the velocity of the person relative to the ground with the appropriate subscripts (2 pts A) b. Determine the velocity of the water in the river relative to the ground. (2 pts A) c. At what angle does Olaf direct his swimming in the water in order to compensate for the flowing water? (1 pt A)
