Physics 12 Kinematics Question.. Please Help! 1. The problem statement, all variables and given/known data A ball rolls off the top of a 12.5m building with a speed of 3.4m/s. How long does it take to hit the ground? What is the range from the base of the building? 2. Relevant equations V = V0 + at V2=V02 + 2ad Avg V = (V = V0) /2 d = V0 + 1/2 at2 3. The attempt at a solution All I've got was a sketch drawn.. Please help me. Well I timed 12.5 by 3.4 to get how long it took to hit the ground but I'm not sure if it is right. I'm guessing to find the range you must need an angle of some sort?
