I believe 45 degree but when I did experiement it yielded best at ~35 degree.

You haven't given enough information. If you have a plank of fixed length, and a smooth transition at the ground (no bounce), the ball will roll the farthest when the plank is vertical, since the ball then starts with the most potential energy.

45 degrees

The impact at the end of the inclined ramp may be using up more kenetic energy at the steeper angle. With a better transition from inclined to horizontal I would expect the angle would increase to nearer 45 deg.

Very interesting. I would have said 45 degrees too.

45 degree is true. because the biggest tan is for 45 degree

i'd say 45 degrees

Downhill.

my guess:
pick a frictionless plane
E = (m) (g) (delta h) potential energy
E = (1/2) m V^2 kinetic energy
I'd say it doesn't matter?
