1. The problem statement, all variables and given/known data A 75-kg man sits in the back of a 120-kg canoe that is at rest in a still pond. If the man beings to move forward in the canoe at .50m|s relative to the shore, what happens to the canoe? 2. Relevant equations The equation they gave me is m1v1+m2v2 = m1v1'+m2v2' I don't get it. 3. The attempt at a solution I didn't really make an attempt. All I have on the paper is (120 kg)(.50m|s) + ... I don't know what to put there. If it's even right!
