whoops... arithmetical error once I fixed it I got t = sqrt(306/.5*9.8*sin(11)) = 18.901, which was correct thank you for the help :)

After a bit more extensive research I found this website: http://www.batesville.k12.in.us/physics/phynet/mechanics/RotMechanics/fall_slide_roll.htm which seemed to explain what you just said, and explained that acceleration = gsin(theta), which makes sense. So taking this into account...

In order to get an appreciation for the time scales involved, think about a block that slides without friction down a ramp that is inclined at an angle q above the horizontal. Initially the block is at rest a distance s (measured along the plane) from the bottom. Click the button marked “DATA”...
