Answer:
The amount of force acting on the spring.
Explanation:
Here, Fspring= kΔx is a equation denoting the amount of force acting on the spring.
where, k = spring constant.
Δx= change in the length of the spring.
so, for every Δx change in spring length, kΔx force acts on the spring.
Answer:
See the answers below.
Explanation:
The magnitude can be easily found by means of the Pythagorean theorem.
We know that the coordinates in x and in y are negative, therefore the vector should be located in the fourth quadrant, see attached image.
And the angle with respect to the horizontal can be determined by means of the tangent of the angle.
These are 40 degrees below the X-positive horizontal axis.
