Dae-hyun, a man of mass 72 kg, steps from a table 92 cm to the floor below. Assume that his velocity is zero as he leaves the table. As he lands, he bends his knees so that he decelerates to a final speed of zero over a distance of 35 cm. (a) What is Dae-hyun's speed just as he starts to hit the floor? Type your answer here (b) As he decelerates, what is the magnitude of the force exerted on him by the floor? Assume constant acceleration. x10 to the power of Type your answer here Type your answer here (You may need to involve some kinematics to solve this one!) m/s N on Dae-hyun.
