You’re stuck on a raft in the middle of a lake. Luckily, you brought your physics book! You decide to use your book to propel you back to the shore. You throw your 1 kg book overboard with a speed of 10 m/s to propel yourself back towards the shore. Assume the combined mass of you and the boat is 100 kg. Part one- How long would it take you to reach the shore after throwing your book? (Ignore friction between the water and the boat.) The shore is 60 m away.

Unfortunately, it starts raining as you float towards the shore. The rain falls
straight down into the boat.

Part 2 (2 points)
10 kg of rainwater has accumulated in the bottom of your boat. What is your speed now?
