 Not all current students are math dummies. Not all 1960's students were math geniuses either. - Clem1640 [more] |

Re: Bouncing TrackBalls
Well basic kinematics shows that the height of each bounce doesn't matter at all for the time that it will take to hit the wall, just the velocity with which it is released as it is hurdled.
The bouncing height will increase the contact/normal force and thus the friction, but the ball wasn't going to be sliding anyway, presumably it would just start rolling. |
