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? a. 305,760 jb. 229,320 jc. 203,840 jd. 588,000 j

A. 305,760 J

Explanation:

Work is defined as a force causing the movement or displacement of an object.

work=

Given: m=  mass = 4 kg

g= acceleration due to gravity =

h = height = 15m

Putting in the values we get,

work=

Now 520 bricks are to be relocated, thus work done =

Thus amount of work will be needed to accomplish the task is 305760 J.

i think it is true since you can test the answer and can use observations to complete it.

b.

the accuracy of the data.
