Here's a fun one:
Consider an incline, which is one part of a circle, radius 'r' m. From one end of an incline(A), to the center O, there is a frictionless plane inclined at an angle of theta. A mass (A) slided down the striaght. slope. Another mass (B) which has the same mass of A, slides down the circular incline from the other end. Determine which mass reaches the center O first. It's better if you show your calculations...You're not guessing, are you? :)
