one-dimensional movement exercise: Two balls are dropped in a vacuum from the same height, but at different times; The second ball hits the ground 1.35 seconds after the first hits the ground. A. from the above information, deduce an expression that allows you to find the difference between your heights (∆h = h2-h1)

A student drops two ball bearings, a lighter one and a heavier one, from a top of a roof. The friction is insignificant. Just before hitting the ground, the heavier ball has twice the kinetic energy. How much faster did it go? so to do this I just did. KE = 1/2 m V^2 2KE = mv^2 so 0.5 faster?
