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.
