Answer:
<em>Net force = 21.12 N</em>
<em>angle for the force α = 45°</em>
Explanation:
<em>In this problem, we will take the left as the negative x-axis, the right as the positive x-axis, and the upward direction as the positive y-axis.</em>
The 20 N force to the left has an x component of -20 N, and y component of 0 N
The 35 N force to the right has a x component of 35 N, and a y component of 0 N
The 15 N upwards has an x component of 0 N, and a y component of 15 N
We resolve the forces into the x and y components.
for the x component Fx
Fx = -20 + 35 + 0 = 15 N
For the y component Fy
Fy = 0 + 0 + 15 = 15 N
Net force Fn = 

<em>Net force Fn = 21.21 N</em>
for the angle,


α =
1
<em>angle for force α = 45°</em>
There are seven fundamental units, out of which two examples of non-vector quantities could be:
1) meter (unit of length)
2) second (unit of time)

Unbalanced because if it is pushing then stopping, that means that it is unbalanced.
