Unformatted text preview: Visual Physics218-lab - Technical Memo To: Tristian Leggett (Physics TA) F rom : Diego Hernando (Student) Date : Thursday, April 24, 2008 Subject: Lab 4 exp 1: Efficiency of the bumper of the cart This experiment was easily done. The purpose of the experiment was to calculate and show the efficiency of the bumper of the cart using the k inetic energy before and after the collision in all three different initial velocities, our results show that the slower the initial velocity the more efficient is the bumper. Experimental results and analysis On ar rangement 1 the initial velocity of the cart was 0.64 m/s2 and the final velocity of the cart was -0.63 m/s2 (look at graph 1)giving us a kinetic energy of 0.061 J and 0.060 J respectively (cart with a mass of 300 grams, formula: K=1/2mv2). Dividing the final kinetic energy with the initial kinetic energy gave us the efficiency of the bumper equal to 0.98. On the second ar rangement the init ial velocity of the cart was 1.2 m/s2 and its kinetic energy 0.216 J, the final velocity of the cart was -1.27 m/s2 and i ts kinetic energy 0.242 J (look at graph 2). The efficiency of the bumper in this case was 1.12. On ar rangement 3 the init ial velocity of the cart was 0.48 m/s2 and i ts kinetic energy 0.035 J, the final velocity of the cart was -0.425 m/s2 and i ts kinetic energy 0.027 J (look at graph 3). The efficiency of the bumper in this third case was 0.77. Conclusion This experiment showed us how the greater the initial velocity of the cart the greater the efficiency of the bumper of the cart, as you can see from the results we got. ...
