A 57.0 kg diver dives from a height of 15.0 m. She reaches a speed of 14.0 m/s just before entering the water. What was the average force of air resistance (e.g., friction) acting on the diver?
What is the force of friction underwater if she reaches a depth of 2.5 m before stopping? Do not neglect the buoyant force of 500 N acting on the diver once underwater
2. Relevant equations
W=change in Ek
3. The attempt at a solution
I’m not sure if I solved for friction properly. The way that I solved here doesn’t work for the next step in the water, so I think initially started wrong.
