Let me see whether I can include such questions (qualitative ones at least) at physicsplus. The problem is that the questions here are expected to be worked out in a relatively short time as in the context of entrance examinations.<BR/>Thank you so much.MVhttps://www.blogger.com/profile/05910408858112321196noreply@blogger.comtag:blogger.com,1999:blog-32436271.post-46591505358158375792007-07-11T19:12:00.000+05:302007-07-11T19:12:00.000+05:30One of my favorite problems is the bowling ball pr...One of my favorite problems is the bowling ball problem - you throw the ball horizontally, not rolling, at the ground with an initial velocity of v_0. It slides along the ground with a given coefficient of friction for an unknown distance and time, and then begins rolling. Find the time and distance to begin rolling in terms of things like μ, g, and v_0. <BR/><BR/>I like this one so much b/c it combines not only 2-D kinematics, but also rotational motion, forces, torque, friction, and just about everything. It's a good one to assess whether a student knows many major topics and can combine them. Even when you've seen and solved the problem before, it's still a challenging problem.zandperlhttps://www.blogger.com/profile/01700239961953729095noreply@blogger.com
