Question

A 68 kg human sprinter can accelerate from rest to 10 m/s in 3.3 s . During the same time interval, a 25 kg greyhound can go from rest to 20 m/s.

Part A

What is the average power output of the human? Average power over a time interval Δt is ΔE/Δt.

Express your answer to two significant figures and include the appropriate units.

Part B

What is the average power output of the greyhound?
