1. The problem statement, all variables and given/known data A 65kg swimmer jumps of a 10m tower. a) Find the swimmer's velocity when hitting the water b) The swimmer comes to a stop 2.0m below the surface. Find the net force exerted by the water. 2. Relevant equations F=ma? I don't know the rest, which is part of the problem 3. The attempt at a solution I'm entirely lost, I can't figure out how to find velocity when you are given mass and distance. I just don't understand. I only got as far as being able to state the data. Please help!
