Study the scenario. A rock is thrown in the air with 1,000 J of energy. The isolated system consists of the rock, the person, and the Earth, ignoring air resistance. At some point on its path up, there is 900 J of kinetic energy in the system. Which choice best describes the amount and form of energy in this system when the rock is at this point?
There are more than 100 J of gravitational potential energy in the system because the rock is at some position relative to the ground, and the total energy must be more than 1,000 J. Some energy is gained during energy transformation.
There are slightly less than 100 J of gravitational potential energy in the system because the rock is at some position relative to the ground, and the total energy will be less than 1,000 J. Some energy is lost during transformation.
All of the energy is in the rock at this point in time is kinetic energy. There are 0 J of any other energy in the system because gravity is not pulling on it at this moment.
There are exactly 100 J of gravitational potential energy in the system because the rock is at some position relative to the ground. There must be a total of 1,000 J of energy in the system because energy is conserved.

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
