Answer:
A) Wn = 90J
B) W1 = 100J
W2 = 10J
Explanation:
A) The net work done on the box is calculated by using the following formula:
[tex]W_n=(F_1-F_2)d[/tex] (1)
F1 = 100N
F2 = 10N
d: distance on which the box is moved = 1m
You replace the values of the parameters in the equation (1):
[tex]W_n=(100N-10N)(1m)=90J[/tex]
The net work on the box is 90J
B) The total work done by each force is:
[tex]W_1=F_1d=(100N)(1m)=100J\\\\W_2=F_2d=(10N)(1m)=10J[/tex]
The first box does a work of 100J and the second force does a force of 10J
