Bob (52.0kg) was curious about the amount of air resistance (friction) that would act on him as he fell through the air, so he conducted an experiment. He stepped out of a hird story window, 15.0m above the ground, and measured that it took 1.94s to hit he ground (don't worry, there was a soft mat to cushion the impact). Assuming his nitial velocity was zero as he stepped out of the window, determine the force of air friction that acted on Bob as he fell.|

Question
3. Bob (52.0kg) was curious about the amount of air resistance (friction) that would act
on him as he fell through the air, so he conducted an experiment. He stepped out of a
third story window, 15.0m above the ground, and measured that it took 1.94s to hit
the ground (don't worry, there was a soft mat to cushion the impact). Assuming his
initial velocity was zero as he stepped out of the window, determine the force of air
friction that acted on Bob as he fell.
