This milestone will provide an additional step toward the completion of the final project. This step should be fully analyzed in the final submission. This milestone represents Critical Elements I, II, IV, and Parts B and C of Critical Element III. Provide an additional step towards the completion of the final project. This step should be fully analyzed in the final submission. Your submission will demonstrate the knowledge of how to calculate the values that give a quantitative description of what is going on during the
selected step and at the transitions to/from the neighboring steps, using the quantitative description as a starting point.
Specifically, the following critical elements must be addressed:
I. Step Selection: Select a step or stage in the Rube Goldberg device. Provide a concise description of the step.
II. Previous Step
B. Equations: Provide the equations that can be used to describe the transfer of energy and the momentum of the object from the previous step to
the selected step. What is the connection between the basic physics concepts in the equations and the interaction of the object and force(s)
from step to step?
C. Calculations: Using the applicable equations you identified, calculate the transfer of energy and the momentum from the previous step to the
selected step. How do these calculations help you predict the object’s location and velocity from the previous step to the step you selected?
III. Selected Step
B. Equations: If applicable, provide the equations that can be used to describe the change in type and amount of energy across the selected step.
C. Energy Calculation: Calculate the amount of energy that is converted from one form to another form using the changes in mass and height. For
example, if appropriate for your selected step, you could calculate the transformation of potential energy to kinetic energy.
D. Velocity and Force Calculations: Calculate the change in velocity that would be observed based on the changes in type of energy. Then, use
Newton’s second law to calculate the force acting on the object.
IV. Subsequent Step
B. Equations: Provide the equations that can be used to describe the transfer of energy and the momentum of the object. What is the connection
between the basic physics concepts in the equations and the interaction of the object and force(s) from step to step?
C. Calculations: Using the applicable equations you identified, calculate the transfer of energy and the momentum from your selected step to the
subsequent step. How do these calculations help you predict the object’s location and velocity from the step you selected to the subsequent
step?
Guidelines for Submission: Submit assignment as a Word document with double spacing, 12-point Times New Roman font, and one-inch margins. Your
paper should be 2- to 3-pages.

Response: I. Step Selection
I have selected a steel ball weighing 1.786 kg, hit by a spiral spring in an inelastic collision setting the ball in motion. The ball rolls down and covers a 2-meter inclined plane board at 45 degrees.
Response: II: A. Behavior Analysis
A compressed spiral spring-loaded with a force of 10N is released to collide with a stationary ball. The compressed spring has potential energy, which is instantly converted into kinetic energy upon release (Shapiro & De Berredo-Peixoto, 2013). The inelastic collision between the spring and the stationary ball transfers the spring’s kinetic energy to the ball, which sets it in motion.
B. Equations
The spring's initial velocity before hitting the ball is (0) because the compressed spring was in a stationary state. Upon release, it accelerates at a velocity of 2.04m/s. The compressed spring measures 0.62m in length. It takes approximately 0.22 seconds for the spring to uncoil, hit the ball, and transfer its kinetic energy. The spring's velocity reverts to 0.0 m/s since it does not recoil back to its initial position.
Final velocity of the coil = final velocity (Vf) = initial velocity (Vi) + acceleration*time
Therefore;
Vf = Vi + at
Vf = 0 m/s + (2.04m/s^2 * .22)
Vf = 0.4488 m/s
C. Calculation of Energy Transfer and Momentum
The potential energy of the spring is equal to:
P. E= ½ k x^2
P.E = ½ (0.0059) (0.62m) ^2
P.E = 0.0011J
Therefore, the compressed spring had potential energy of 0.0011mgh. Hence, the amount of energy lost or transferred to the ...
