    Angular momentum and perfectly inelastic collision

    Ok! I never even thought of the possibility that it wasn't vertical. So now my thinking is to use torque = 17 N * .025 m and divide that by the moment of inertia MR^2 to get angular acceleration. Then I can just use simple kinematics. Does that sound correct?

    Angular momentum and perfectly inelastic collision

    When the ball collides with the catcher, does the system lose some kinetic energy as well?

    Angular momentum and perfectly inelastic collision

    Hi, I just don't really understand rotational motion very well, and I don't know how to proceed with this problem. Homework Statement You throw a 235 g ball 26 m/s at the apparatus shown in the figure. http://volta.byu.edu/ph121/homework/hw18f3.png The apparatus catches the ball, causing it...

    Conservation of Angular Momentum with Changing mass

    Oh ok, that makes sense. Thanks again!

    Conservation of Angular Momentum with Changing mass

    Thank you both very much. That is exactly what I needed! My only question would be how did you know what the moment of inertia would be for that system?

    Conservation of Angular Momentum with Changing mass

    I am completely stuck on this problem, and was wondering if anyone could point me in the right direction. Homework Statement In the spinning fireworks display shown in the figure the ignited gun powder is ejected from the jets at a speed of 24.3 m/s...
