A 2-HP winch is used to raise loads of bricks up a 30 meter building. If the bricks need to get to the top of the building in 2 minutes, what is the maximum allowable mass of a load of bricks?

600 kg

Explanation:

First, convert horse power to SI units.

2 HP × (745.7 W / 1 HP) = 1491.4 W

Power = work / time

Power = force × distance / time

1491.4 W = m × (9.8 m/s²) × (30 m) / (120 s)

m = 609 kg

Rounding to one significant figure, the maximum allowable mass is 600 kg.
