Answer to Question #137511 in Classical Mechanics for john michael abaricia

Question

A laborer brings 2 bags of cement up to the second floor of the building. In Each bag, he applies 230 N. If the height from 1st floor to the 2nd floor is 10 m, what is the work of the laborer?

Answer 1

Solution

Given data in the question

Force on each bag=230 N

There are two bags so total force become

F=$2\times230=460N$

Height from 1st floor to 2nd floor is

H=10m

Work of laborer is

$W=F\times H$

$W=460\times10$

$W=4600J$

Therefore work done by laborer is 4600J.
