Note that the screw-adjusted mechanism changes its length by 1/32 of an inch for every 360 degree turn of the screw. Set up a ramp with the screw-adjusted mechanism at the top to change the slope of the ramp. Measure the delta S and the time and use this to find velocity and then use the delta v/delta t to get the acceleration. The screw-adjusted mechanism changes the slope of the ramp so take this into account. 5.If a larger steel ball collides center to center with a smaller ball, what are the velocities before and after collision? According to your results, assuming that momentum is conserved, what is the ratio of the masses of the two balls? Set up two ramps and let the last ramp level off, and at the end of the second ramp put a tee holding the small ball while the bigger ball rolls down the ramps. The balls should hit each other at about the center. You should also use about 4 dominos to prop the first ramp up, and when the balls hit the ground we can collect the delta S and more data, then we analyze. 12.To what extent is the motion of a mass suspended from the end of a steel spring similar to that of a mass suspended from a rubber band? Set up both a spring and rubber band attached to a plastic bag containing the same number of dominos. You measure to see how much each one streatches from the start and at the end. Then you can compare the data to see similarities and differences.
