A 65 kg person dives into the water from the 10 m platform. a. What is her speed as she enters the water? (Hint: Think freefall.) h=12mm=65 kg V= 2⋅9.8⋅10​V= 196 V=14 m/s b. She comes to a stop 2.0 m below the surface of the water. Sketch a force diagram of the diver and a kinematics stacks at right. c. What sum force did the water exert on the swimmer? What direction is this sum force?
