Physics 211 10/31 HW Handout Name_____________________ Fall 2001 Bowling Ball Race Due Friday 11/2 1) Paul has fifteen bowling balls of mass m stacked on a frictionless sled, also of mass m, that is at rest. Paul’s mass is 8 m so the total mass starts out at 24 m . By throwing bowling balls off the back, Paul is able to get the sled (with Paul and balls) in motion. a) If the first ball is thrown so that the ball’s final velocity is v, what is the impulse applied to the ball? Show your reasoning. Include a momentum diagram. b) What is the velocity of the sled after the first ball is thrown? Show your reasoning,

Unformatted text preview: including a momentum diagram. c) Assuming Paul applies the same impulse each time, what is the velocity of the sled after the second ball is thrown? Careful, it’s not twice that in part b. Show your reasoning, including a momentum diagram. Hint: Find ∆ v and add it to v sled from part b. d) What if he keeps it up till all the balls are gone? How fast are he and the sled going now? Hint: Find ∆ v for each toss and add them all up. This will be a bunch of fractions so you can leave it that way or add them as decimals. Show your reasoning. 8 m m 24 m = initial mass of the system...

### What students are saying

• 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.
