That gives me a KE of 3/5mgh, so the new (final) height will be 3/5 the original height. Force of spring = K times change in x. K(r) = 1/2mv^2^ + 1/2(mr^2^ )·(v/r)^2^ Physics. For part 1, I got the math down to the square root of 2gh, because I assumed they were just asking for Vfrictionless. mgh = 1/2mv + 1/2Iw. v = ± โ2mghm m v = ± 2 mg h m m The complete solution is the result of both the positive and negative portions of the solution.
์์ ๊ต์ค Pdf If the vertical drop is h, then the potential energy at the top is mgh. I am not sure if this is correct but this is my basic idea.
