1. The problem statement, all variables and given/known data Hello, new here. I'm doing homework for my Honors Physics class, and I have a kinematics problem that seems simple enough, but I just can't get it. Help, please? A ball is rolling on a table 1.225 m high at 6 m/s. After it rolls off, how long does it take to hit the ground? 2. Relevant equations I used V^2= (Vo)^2 + 2a(X-Xo) to find final velocity, than used V= Vo+at to find time. 3. The attempt at a solution V^2= (6 m/s)^2 + 2(9.8 m/s^2)(1.225 m) V= 7.7 m/s t= (V-Vo)/a = (7.7 m/s - 6 m/s)/ 9.8 m/s^2 t= .17 s I know this is wrong. My physics teacher told me to use Vx, not Vy, for Vo. I'm not quite sure how to go about this. Do I need to find the angle (which I'm not sure how to do in this problem) and use Vox= Vocos(theta)? Any help would be appreciated.
