You are riding on a Jet Ski at some angle upstream on a river flowing with a speed of 2.8 m/s (a) Suppose the Jet Ski is moving at a speed of 11 m/s relative to the water. At what angle must you point the Jet Ski if your velocity relative to the ground is to be perpendicular to the shore of the river? (Note: Angles are measured relative to the x axis shown in the figure.) Express your answer using two significant figures. (b) If you increase the speed of the Jet Ski relative to the water, does the angle in part A increase, decrease, or stay the same? Explain. (c) Calculate the new angle if you increase the Jet Ski speed to 15 m/s. Express your answer using two significant figures.
