A solid ball and a hollow ball, each with a mass of 2 kg and radius of 0.1 m, start from rest and roll down a ramp of length 3 m at an incline of 44°. An ice cube of the same mass slides without friction down the same ramp.

What is the speed of the ice cube at the bottom of the incline?

I've using the equation mgh = (mv^2)/2, but I end up with the wrong answer. Any help is greatly appreciated

Never mind, I figured this out.
