1. The problem statement, all variables and given/known data 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 Eg=mgh Ek=(1/2)mv^2 Et=Ek+Eg W=Ef-Ei W=change in Ek W=fd 3. The attempt at a solution Ek=(1/2)(57kg)(14m/s)^2 =5586J W=Ek =5586J-0J W=fd 5586J=F(15m) 5586/15=F F=372.4N Fnet=ma =(57kg)(9.8N/kg) =558.6N Fnet=558.6N Fapp-Ff=558.6N 372.4N-Ff=558.6N Ff=186.2N 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.
