Physics is a class, taught by Mr. Ellis, which teaches about various parts of physics on an advanced track. Over this past year, we have learned a variety of things, starting with kinematics and now continuing on to rotational concepts. Our general physics schedule is that we are assigned a new unit, get all the notes and go over them while doing various sample problems, work on end-of-chapter questions, work on multiple practice tests, and then take the test for the unit. While doing all of these assignments we are encouraged to work collaboratively with our peers. With some of our units, we have done “uber” problems which are long problems that require multiple stages to be solved. I have attached two below along with further information on them.

uber pulley

This assignment is my uber pulley which is a problem from the forces unit. In this problem, a ramp and pulley system is used in order to pull a luge up a ramp. The luge then flys off the ramp and acts as a projectile until it reaches the ground. Once it reaches the ground, it finishes off by sliding a certain distance. The goal of this problem was to use the given information in order to find the coefficient of friction between the luge and the ground during the final part of the luge’s motion. For further clarification, I suggest looking at the diagram in the attached assignment as well as the listed givens and outlined steps.

uber rocket

This assignment is another uber problem, this time being the uber rocket problem for the kinematics unit. In this problem, a hamster named Huey is launched inside a model rocket (safely). The rocket is launched from rest at a specific angle and is only designed to last for a specific amount of time. After this time is up, the rocket continues to stay in motion, this time as a projectile. Once the rocket reaches a specific distance above the ground, a parachute opens up and the rocket then falls to the ground with the wind now affecting its movement. The goal of this problem is to calculate the total x-displacement of the object. Once again, further clarification can be provided by looking at the diagram, equations, and outlined steps.
