I can't see the screw (if you'll pardon the expression), so I don't know a thing about it, and can't answer the question. There's no given information in the question.
The net force simply the sum of two forces:
Negative and positive are assigned to those forces to show direction because it is a vector.
So, given that left is negative and right is positive;
<em>a)</em>
2.30N - .800N = 1.50 N
Given the equation F = ma, where m= 0.125 (mass) and F = 1.50 (force), we can solve for a (acceleration).
<em>b)</em>
1.50 N = (0.125 kg) a
a = 12.0 ms^-2
Answer:
direction is given as
South of West
Explanation:
Part b)
displacement is given as
now we will have
total displacement is given as
direction is given as
South of West
