SUMMARY
Rosie's power output when pushing a box can be calculated using the formula P = W/T, where W is work done and T is time taken. Given that Rosie exerts a horizontal force of 170 N and moves at a speed of 16 m/min (0.2667 m/s), the power output is determined to be 2.06 W. The discussion emphasizes the importance of using the correct units, noting that Watts are equivalent to N-m/s, and highlights the relationship between force, distance, and velocity in calculating power.
