Momentum
...Therefore since V = d / t: M before ( d / t ) = M after ( d / t ) As stated above we eliminated time by making the carts hit the books at the same time, so now we get: M before D = M after D This is how we are able to make the momentums of carts of different masses equal. Procedure: Trial One Step(s) 1. Weigh both carts to make sure they have equal mass. Skip step 2 if u do not have a problem. 2. Place grams of weight on the lighter cart until both carts have equal mass. 3. Place carts back to back on a level surface, making sure the velocity rod on the one cart touches the other. 4. Measure a distance of 1 meter from the edge of first cart, and place heavy book at the end. 5. Repeat step 4 for other cart. 6. Using a long stick, tap the button on the cart, to put both carts in motion. Trial Two Step(s) 1. Place a 50 gram weight on the second cart. 2. Place carts back to back on a level surface, making sure the velocity rod on the one cart touches the other. 3. Measure a distance of 1 meter from the edge of first cart, and place heavy book at the end. 4. Measure a distance of .66 meters from the edge of second cart, and place heavy book at the end 5. Using a long stick, tap the button on the cart, to put both carts in motion. Trial Three Step(s) 1. Place a 200 gram weight on the second cart. 2. Place a 100 gram weight on the first cart. 3. Place carts back to back on a level surface, making sure the velocity rod on the one cart touches the other. 4. Measure a distance of 1.5 meters from the edge of first cart, and place heavy book at the end. 5. Measure a distance of 1 meter from the edge of second cart, and place heavy book at the end 6. Using a long stick, tap the button on the cart, to put both carts in motion. Data: Trial One Mass of first cart: 100 grams Mas...
