Q4 A boat, which can reach a maximum speed 2.50 m/s in still water. When the captain heads the boat directly to reach opposite bank of the river, he arrives at a point 236 m upstream from where it starts (see Fig). He calculated that the boat must be headed bat a 45.0° upstream angle to reach the exactly opposite bank of river. What is the speed of the river's current? 236 m Finish River current 570 m 45.0 Start

4. Swims across Lake Erie are officially sanctioned by the Lake Erie Open Water Swimming Association. Your friend on the swim team wants to swim across the lake. The plan is that your friend will swim to Presque Isle starting at a location at Long Point, Ontario which is 24 miles due north of Presque Isle. You will be navigating a boat with a GPS. Your friend can maintain a speed of 1.80 mph in still water. All during the swim you observe that objects drifting in the water are moving at 0.70 mph to the east due to the current. a. What bearing should you maintain? That is what direction should you point the boat to reach Presque Isle? Give your answer relative to a compass direction (i.e., 30° north of west). Hint, you want your net velocity vector to be straight south. b. How long did it take your friend to swim across Lake Erie? c. What is the addition amount of time that your friend will need to swim compared to if there was no current (assume your friend swims at a constant rate)?
