Free Fall Trajectory So I am basically lost in what that means. I think it is the component method for vectors? Am I right? Some background on the lab: We rolled a marble down a curved ramp so that it went off the table and hit the ground in front of the table. (we marked where it hit with carbon copy paper. I already measured the potential energy and velocity. 1. The problem statement, all variables and given/known data Question: Recalculate the horizontal marble velocity of the marble at the bottom of the track using the free fall trajectory method. The height of the curved track from the table was 14.3cm and the height from the table to the ground was 84.4cm And the distance that the marble traveled from the edge of the desk was 44.5cm mass of marble = 13.7g Do I need the length of the track? 2. Relevant equations (THis is what I am looking for) 3. The attempt at a solution If someone could explain what free fall trajectory method is (my teacher doesn't teach, he just talks). That should be enough to point me in the right direction. Also if it is the component method, then i would need the angle of the ramp, correct? Thanks!
