    Help with free falling object problem

    nope, that's the question. I'm fairly sure it involves finding a ratio, due to the many unknowns, so I imagine finding the value of H is not the goal. It's also assumed to be no air resistance. The two balls are released or dropped, so Vo = 0 m/s for both balls. Show some work? OK...

    I hope this is the right forum, so I apologize in advance if I'm mistaken. Here's the question poised: How many seconds apart should two balls be released so that a ball being dropped from a height of H reaches the ground at the same time as a ball dropped from a height of 5H? I need...
