Ramp experiment 080929

Obtain the data necessary to find right-left and left-right accelerations of the ball on a ramp lying on table. Specify the orientation of the ramp (e.g., north-south, east-west, etc.).

Find the horizontal range of the projectile for a ramp supported by 1, 2 and 3 dominoes. Use a short horizontal ramp at the end of the sloped ramp to redirect the velocity so that the initial velocity of the projectile is horizontal. Also make observations necessary to find the time required for the ball to accelerate down the ramp (assume uniform acceleration).

For each setup find the velocity of the ball as it leaves the end of the last ramp, based on your observations of the projectile motion.

Based on your timing of the ball on each ramp, what is the final velocity on each? To what degree is this consistent with the results obtained from the projectile motion? As best you can, in the greatest detail possible, explain any discrepancy between these results.
 

Find the ramp with the smallest slope such that a ball going up the ramp will smoothly stop then roll back down (if the slope is too small the ball's motion near the stopping point may be a little jerky rather than smooth, due to small surface irregularities on the ramp).  Give the ball a nudge and time it up and down the ramp.  Observe the distance it moves up the ramp before turning around.  Find the difference in accelerations up and down the ramp.
