An older sample exam 2 with more of an even distribution of problems You will find actual numbers here, because this is the format of the test for that particular semester. Still, this semester, Spring 2004, no number calculations will be required. #1 The shank of the vertical plunger of weight W1 (=5-lb) (marked P ) occupies the dashed position when resting in equilibrium against the spring of stiffness k . (In this position it rests d1 (= 0.25 in). above the button A. The upper end of the spring is welded to the plunger, and the lower end is welded to the base plate. If the plunger is lifter d2 (=1.5 in). above its equilibrium position and released from rest, calculate its velocity v just before it strikes the button A. Friction is negligible. (20 points) #2 Consider again the physical situation in problem 1. The button is welded to a base, and together they are much more massive than the plunger. If the coefficient of restitution is e (= 0.8), what is the speed of the plunger just after it has hit the button? (10 points) If you have not

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
