Homework Help: Physics Lab

Posted by Heather on Friday, November 12, 2010 at 3:55pm.

We have a metal ball and a ramp that we can clamp to the edge of a table. We are supposed to find the coefficient of friction between the ball and the ramp. We think we should use projectile motion and the law of conservation of energy. We don't know what to do with them however because we are not allowed to use timers. How should we do this?
