No need to edit anything above the Result page. Thanks!
1. Calculate the μs in the result table. (highlight in doc)
2. Redraw or add to the diagram showing the force. (the feedback from the tutor for the originaldiagram: When drawing this free body diagram all forces should be acting on the centre of the object. If R were acting on the bottom of the box at that point it would create a rotation and flip the box. Same thing goes for the force due to friction.
Your forces also need to be to scale (larger forces should be drawn larger). From this diagram, it looks as if friction is large that the force due to gravity down the ramp and the perpendicular component of the force due to gravity is larger than mg. )
3. Recalculate: What is the net force acting on the object in the case you have just drawn?
Calculate the component of the gravitational force acting parallel to the slope just before the object
starts to move (for the case with the highest mass). Calculate the normal reaction force experienced by the object on the slope just before it starts to move
(for the case with the highest mass).
4. Do you expect μs to depend on the mass inside the box? Explain why or why not.
5. Plot a graph of μs versus mass. Does this graph agree with your expectation? Why or why not?

This is a physics homework assignment. There are 15 problems. I will have to copy and paste the problems.

## First, complete everything required from the file called “PHY221_Work-Energy_The

First, complete everything required from the file called “PHY221_Work-Energy_Theorem_Spring21.pdf” with the help of the compressed zip file called “Work Energy Theorem Fall 2020.zip”. The compressed zip file has a file that will help with the “PHY221_Work-Energy_Theorem_Spring21.pdf”. It is just a capstone file. Then once you have finished the lab move the information to look alike to the Lab Report file.

## 1) A sinusoidal transverse wave is traveling along a string in the negative dire

1) A sinusoidal transverse wave is traveling along a string in the negative direction of the 2-axis.
The figure below shows a plot of the displacement as a function of position at time t = 0; the scale of the
y-axis is set by % = 4.0 cm. The wave speed along the string is v = 12 m/s.
Find the:
(a) Amplitude A,
(b) Wavelength A,
(c) Period T,
(d) The maximum speed of a string particle,
(e) Wavenumber k
(f) Angular frequency w,
(g) Phase constant do,
(h) The correct choice of sign for the wave direction.
2) A ID potential energy with a stable equilibrium point may be, as long as the displacement
from the equilibrium is very small, approximated as the same form as that of a potential energy of a simple
harmonic oscillator, i.e. the same potential energy as that of a spring-mass. How so? Hint: Consider a
general, infinitely differentiable U(2), and what its form is very close to the equilibrium point teq.
