Superman can leap over tall buildings in a single bound. What does he do to the ground beneath him? Assume his mass is 100.0 ± 0.1 kg and his hips drop by 0.300 ± 0.020 m before he jumps. If he can jump over the top of PNC Plaza (tallest building in Raleigh), which is 164 ± 1 m, calculate the following with uncertainties:
a. Takeoff velocity
b. Acceleration just before takeoff
c. Force on ground at take off
