A swimmer has just jumped off a diving board. The swimmer has a mass of m = 56.4 kg and jumps off a board that is h = 7.15 m above the water. Exactly T = 4.1 seconds after entering the water, her downward motion is stopped. a) Write an expression for the magnitude of the average upward force Fw exerted on her by the water in terms of the variables given in the problem statement and g (9.80 m/s2). b) What is the magnitude of the average upward force Fw (in N) exerted on her by the water?
