Thanks for the reply, I'll get to the equations tomorrow as it's quite late at the moment.

When the arc is too small, the angle will differentiate at a much faster rate which will result in a bigger energy loss. We're going to try and keep the friction as small as possible by covering our ramp in a non-friction product. We're a bit unsure whether the ball would be rolling or sliding...

Homework Statement We're assigned to build a ramp that launches our ball as high as possible. For now we're not taking any friction into account. Max height: 120cm Image: http://i.imgur.com/4DmX0mZ.png Homework Equations v = g * t Ep = m x* g * h Ek = (1/2) * m * v^2 The Attempt at a...
