If a completely cylindrical bar with a mass of 5000kg is flung into a wall with a surface area of 500un^2 and is morphed into a square at 50NMC/m at 40 degrees tangent to the area of initial impact. What is the length of the sides?

Third year?

Try drawing all the vectors and their rates for EACH stage and see if that helps.
Your final answer should be:
24.2m
If you still can't get it don't be afraid to ask for an explanation.

I get:

VecA=40m/s
VecB=62.2m/s
VecC=33.4m/s
VecD=199.3m/s
all at E of S of the radius

Then
VecE=27.8m/s at N of W
And
VecF=101.1m/s in a linear spiral

Final= 1.87m
Which of my vectors are wrong?

Your F stage vector should be 784.3m/s in a spiral is correct.

My guess is you didn't take [4(pi)SA^3] when finding F (:

Thank you so much!!! This problem gave me a headache!

To find the length of the sides of the square formed when the cylindrical bar is morphed, we need to follow a step-by-step process:

Step 1: Calculate the force applied to the wall.
The force applied to the wall can be determined using the formula:

Force = mass x acceleration

In this case, the mass of the cylindrical bar is given as 5000 kg, and we need to find the acceleration. However, the acceleration is not provided in the question, so we cannot calculate the exact force. If you have the acceleration value, you can substitute it into the formula to find the force.

Step 2: Determine the area of contact.
To find the area of contact with the wall, we need to know the shape of the cylindrical bar. However, the question states that it morphed into a square upon impact. Therefore, we can assume that the area of contact is a square with equal sides.

Step 3: Solve for the side length of the square.
Given that the area of contact with the wall is 500 square units (500un^2), we can use the formula for the area of a square to solve for the side length.

Area = side length^2

Substituting the given area, we can rearrange the formula:

500 = side length^2

Taking the square root of both sides, we find:

√500 = side length

Simplifying the square root, we get:

Side length ≈ 22.36 units

Therefore, the approximate length of each side of the square formed when the cylindrical bar morphs is 22.36 units.
