Materials: Launch ramp, two metal marbles ( m 1 = 8.5 grams), one glass marble ( m 2 = 3.4 grams) OR one large marble ( m 2 = 19 grams), meter stick, notebook paper, carbon paper, and masking tape. Directions: 1) Clamp the ramp to the end of the table. Turn the ramp so that it is NOT pointing directly at the pedestal screw. Place a metal marble at the top of your ramp, and release it. The marble should NOT pass over the screw, but instead pass to the side. Observe where on the floor the marble lands. 2) Tape your notebook paper on the floor with its center at the marble’s landing point. Place the carbon paper on top of the notebook paper, with the black side down and the gray side up. 3) With a piece of tape, mark the spot on the floor directly below the end of the ramp. This is the “origin” 4) Repeat step #1 ten times. When the marble hits the carbon paper, it should make a dot on the notebook paper. 5) Remove the carbon paper, and locate the approximate center of the clump of dots. 6) Measure the horizontal length of the displacement vector from the origin to the center of the clump of dots. Record this as x o . 7) Place a meter stick on the ground along the line from the origin through the clump of dots. Place a piece of tape on the ground at the end of the meter stick. This is the “endpoint”. The line from the origin to the endpoint is the x-axis of the experimental coordinate system. 8) Place the other metal marble on the pedestal screw at the bottom of the ramp. This is the “target” marble. Roll the metal marble down the ramp. This is the “incident” marble. Carefully observe the collision. 9)
