Question

2) A person, Person A, pushes a 35.0 kg foam block 5.00 m in 4.00 s. Another person, Person B, does the same thing in 2.00 s. What is the power output of each Person? Ignore the power needed to stay alive at rest (the 100 resting Watts).

3) The average human, at rest, produces around 100 watts of power. [2] Over periods of a few minutes, humans can comfortably sustain 300-400 watts; and in the case of very short bursts of energy, such as sprinting, some humans can output over 2,000 watts. What is the maximum mass of a block that an exceptional human can move under these circumstances?
