1. You decide to take the ferry across Lake Michigan. The ferry makes the 136 km trip in 2.5 hrs, giving an average speed of 15 m/s in still water (no wind). You got on the ferry in Muskegon, MI, so you're heading west (it's actually really close to exactly west). While on the ferry, you walk from the back to the front at a speed of 2 m/s. On this particular day, the wind is blowing hard, creating a sort of current that goes west-to-east at a rate of 3 m/s. When you pass a buoy (which is anchored to the bottom of the lake), what is its speed relative to you? 2. You need to cross a river, but the river has a current. There's a waterfall nearby, so it's really important that you make it directly across the river without drifting downstream. You have a small fishing boat with a motor that can reach speeds of up to 5 m/s relative to the water. You happen to know that the current is quick here, having a rate of 4 m/s. At what angle should you point your boat to make it directly across the river? 1. You decide to take the ferry across Lake Michigan.
