You will use this for Levels 1 to 3. A 5 kg bowling ball is moving toward one last bowling pin at a speed of 6 m/s. The bowling pin has a mass of 1 kg and is staying still. After they
collide, they experience an inelastic collision and both the ball and the pin move at some unknown speed.

Equation: mqV1 + m2v2 = myV1,f+ m2v2,f (different final velocity)
m1v1 + m2v2 = m1vf + m2vf (Same final velocity)

Question 1
Level 1:
Calculate the momentum for the 5kg bowling ball moving at 6 m/s

Question 2
Level 2:
Which of the following is the correct way to label the conservative of momentum equation?
A: (5kg)(6 m/s)+(1kg)(0 m/s)=
(5kg)(vf) +(6kg)(vf)

B: (5kg)(0 m/s)+(1kg)(6m/s)=
(5kg)(vf)+(1 kg)(vf)

C: (5kg)(6m/s)+(1kg)(0 m/s)=
(5kg)(vf)+(1kg)(6m/s)

D: (5kg)(6 m/s)+(1kg)(0 m/s)=
(5kg)(vf)+(1kg)(vf)

Question 3
Level 3:
Using the equation you chose before, calculate the final velocities of the bowling ball and the bowling pins.

Level 4: Let’s say that you now use a bowling ball was now 6kg and moving at 12m/s before hitting the bowling pin. The bowling pin is now 2 kg and staying still. Your friend makes a prediction using conservation of momentum. He claims that the bowling ball and the pin must both be moving at 6 m/s after colliding.

Question 4:
You find out that your friend’a claim was inaccurate. Why was their claim correct?

Question 5:
How could you change there initial velocity of the bowling ball to ensure that your friend was correct in the claiming that the final velocity is 6m/s?

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?
