101 20. The law of conservation of momentum applies to any collision between two objects that occurs in
an isolated system. Assuming that the collision between Object A and Object B occurs in an
isolated system, which of the following statements are consistent with this law?
14
a. Object A's momentum before the collision is the same as it is after the collision
b. The change in Object A's momentum will be equal and opposite to the change in Object B's
C. The total momentum of Objects A and B will be the same before and after the collision
d. Object A will not have its momentum altered during the collision
e. Object A will have the same momentum as Object B both before and after the collision

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?
