1. The problem statement, all variables and given/known data A marble is accelerated to a horizontal velocity of 0.50 m/s by rolling it down a small ramp. The marble rolls off the table, which is 0.78 m high. As it falls, it hits a barrier on the way down. If the barrier is 0.15 m from the edge of the table, at what height from the ground, h, will the marble hit the barrier? 2. Relevant equations d = (Vi)(t) + 1/2(a)t/2 Vf =Vi + at (Vf)2 = (Vi)2 + 2ad 3. The attempt at a solution I wasn't really sure how to start it, but first I found the time it would take for the marble to fall off the table: Using vertical components: d = (Vi)(t) + 1/2(a)(t)2 -0.78 = (0)(t) + (1/2)(-9.8)t2 -0.78 = -4.9t2 t = 0.40s I don't know if that ^ is right, and I'm not really sure what I should do next. Any help would be greatly appreciated!
