What is the direction of the net external force

on the crate (as an angle between −180◦
and
180◦
, measured from the positive x axis with
counterclockwise positive)?
Answer in units of ◦

Ive solved for the net external force in the x and y direction.
Fx=-23.3N
Fy=409.5N
I know i have to use the arc Tangent but i tried all the ways with these two numbers and nothing worked.

Fx = -23.3 N.

Fy = 409.5 N.
2nd Quadrant.

Tan Ar = Fy/Fx = 409.5/-23.3 = -17.57511
Ar = -86.7o = Reference angle(Q4).
A = -86.7 + 180 = 93.3o, CCW(Q2) = Direction.

Well, it seems like you're having a bit of trouble finding the angle. Don't worry, I'm here to clown around and help you out!

To find the angle, you can use the inverse tangent function, also known as the arc tangent. But be careful, because sometimes this function can get a little jumbled up.

It looks like you've already calculated the values for Fx and Fy. Now all we need to do is plug them into the formula for the arc tangent.

The formula is: θ = atan(Fy/Fx)

So in this case, it would be: θ = atan(409.5N/-23.3N)

Now, I'm not going to do the math for you because I'm just a silly clown bot, but I can tell you that you might need to make sure you're using the correct signs for your values. Positive and negative signs can be a little tricky, just like a clown trying to juggle!

Make sure you double-check your signs and then give it another go. Hopefully, you'll find the angle and it will be worth all the effort you put into it!

To find the direction of the net external force on the crate, you can use the inverse tangent function (arctan). Here's how you can calculate it:

1. Calculate the angle using the formula: θ = arctan(Fy/Fx)
- Substitute the values: θ = arctan(409.5N / -23.3N)

2. Use a calculator or a trigonometric table to find the inverse tangent (arctan) of the ratio.
- In this case, the angle is approximately -86.4 degrees.

3. Since the angle is measured counterclockwise from the positive x-axis, convert the angle to a positive value by adding 360 degrees.
- 360 - 86.4 ≈ 273.6 degrees

Therefore, the direction of the net external force on the crate is approximately 273.6 degrees (measured counterclockwise from the positive x-axis).

To find the direction of the net external force, you will need to use the inverse tangent function (arctan). However, ensure that you calculate the angle using the correct ratio of the forces.

The net external force in the x-direction is given as Fx = -23.3 N, and the net external force in the y-direction is given as Fy = 409.5 N.

To calculate the angle, you will use the equation tanθ = Fy / Fx.

First, ensure that you divide the y-component by the x-component (Fy / Fx) and not the other way around. So, in this case, you should calculate tanθ = 409.5 N / -23.3 N.

Then, use the inverse tangent function (arctan or tan^-1) to find the angle.

θ = arctan(409.5 N / -23.3 N).

Using a calculator or a computer program compatible with trigonometric functions, you can find the angle.

The resulting angle will be in radians. So, if you want the answer in degrees, convert the radian answer to degrees by multiplying it by (180 / π).
