A 61.7 kg canoeist stands in the middle of her canoe. The canoe is 3.9 m long, and the end that is closest to land is 2.5 m from the shore. The canoeist now walks toward the shore until she comes to the end of the canoe. Suppose the canoeist is 3.4 m from shore when she reaches the end of her canoe. What is the canoe's mass?
I don't know
The Attempt at a Solution
1.95m/.9m * Mp
I tried taking a ratio of how far the canoeist moved to how far the canoe moved in the opposite direction and multiply that by the mass of the conoeist. I got 133.68 kg but that's wrong. How do I do this problem?
