A bricklayer lifts bricks to the top course of a long wall she is building 1.48 m above her wheelbarrow. Assuming she can generate 154 W of useful power, how long will it take (not counting breaks and reloading time) to lift up 2,032 kg of bricks?
Added by Eric L.
Step 1
Work = Force x Distance The force required to lift the bricks can be calculated using the formula: Force = mass x gravity Given: mass = 2032 kg gravity = 9.81 m/s^2 Force = 2032 kg x 9.81 m/s^2 Force = 19922.92 N Now, calculate the work done: Work = Force x Show more…

A load of bricks at a construction site has a mass of $75.0 \mathrm{~kg}$. A crane with 725 W of power raises this load from the ground to a height of $45.0 \mathrm{~m}$ at a low constant speed. How long does it take to raise the load?
What power is needed to lift a $350-\mathrm{kg}$ crate of bricks from the ground to the top of a 23.8 -m-high building in 1 minute?
Working at this rate, how long (in s) will it take this person to lift 1500 kg of bricks 1.70 m to a platform? (Work done to lift his body can be omitted because it is not considered useful output here.)
