Amoving company is called into a building and asked to relocate 520 bricks to a location 15 meters above the ground. if each brick is 4 kilograms, what amount of work will be needed to accomplish the task?

The total weight of the load is (mass) x (gravity) x (height) .

Weight = (520 x 4kg) x (9.8 m/s²)

Weight = (2,080 kg) x (9.8 m/s²)

Weight = 20,384 newtons

Work = (force) x (distance)

Work = (20,834 N) x (15 m)

Work = 305,760 Joules

W = 305760 J

Explanation:

Force required to pull each brick is given as

here we know

m = 4 kg

now work done to bring one brick to height of 15 m

Now company has to transfer total 520 bricks

so total work done is given as

measure their densities same density, same sub
