Question
I know that if a ramp is steeper, larger theta, then the object rolling down will become faster. However, if the object is rolling up the ramp will it slow down like I think it should?
How can I prove this?
When I try to prove it via a kinetmatics equation I keep getting that the final velocity would be greater for a larger theta.
Please help.

Answers
look at the kinetic energy
for rolling up
... the steeper the ramp, the faster the KE becomes gravitational PE
same holds true for rolling down, except the energy goes in the other direction
