Two horizontal forces Upper F1 Baseline and F2 act on a 3.6 kg disk that slides over frictionless ice, on which an xy coordinate system is laid out. Force F1 is in the positive x direction and has a magnitude of 7.1 N. Force F2 has a magnitude of 9.3 N. The figure here gives the x component vx of the velocity of the disk as a function of time t during the sliding. What is the angle between the constant directions of forces F1 and F2?
To find the angle between the constant directions of forces F1 and F2, we need to analyze the given information.
First, let's break down the problem:
1. There are two forces acting on the disk: F1 and F2.
2. Force F1 is in the positive x-direction and has a magnitude of 7.1 N.
3. Force F2 has a magnitude of 9.3 N.
4. We have a graph showing the x-component of the velocity (vx) as a function of time (t).
Now, let's focus on finding the angle between the constant directions of forces F1 and F2:
1. Identify the x-component of force F1: Since force F1 is in the positive x-direction, its x-component is simply the magnitude of F1 itself, which is 7.1 N.
2. Identify the x-component of force F2: As the problem mentions nothing about the direction of F2, we assume it is not in the x-direction. Therefore, the x-component of F2 is 0 N.
3. Since the x-component of force F2 is 0 N, the angle between the constant directions of forces F1 and F2 is either 0 degrees (if F2 is in the positive y-direction) or 180 degrees (if F2 is in the negative y-direction).
In summary, without additional information about the direction of F2, we cannot determine the exact angle between the constant directions of forces F1 and F2. We need more information to solve the problem.
