1. The problem statement, all variables and given/known data A 50 kg diver enters the water moving at 4 m/s. He eventually comes to a stop 3 meters below the water surface. What amount force brought the diver to a stop? 2. Relevant equations Is the acceleration -9.8 m/s^2? Then, would you use F = ma to find the net force? 3. The attempt at a solution i tried to do F = (50 kg)(-9.8 m/s^2) but i don't think that's right... Thank you.
