PHYSICS 195L LAB REPORT - LAB 8: BALLISTIC PENDULUM 4 3.62m/s 5 3.63m/s Average 3.62m/s Analysis 1. What is the percent difference between your calculated launch velocity from Table 2 and your average launch velocity from Table 3 ? ((3. 62 − 3. 36)/(0. 5)(3. 36 + 3. 62) * 100 = 7. 4% 2. Which method of finding the launch velocity do you think is more accurate? Why? Manuel's measurement of launch velocity because each trial gave the same launch velocity 3. Calculate the percentage of the total kinetic energy that is lost during the collision with the pendulum. ( ). 0. 2552(0) + (0. 07)(3. 36) = 0. 324𝑣 = 0. 726?/? ?𝐸𝑖?𝑖?𝑖𝑎?: 0. 5(0. 2552)(0) 2 + 0. 5(0. 07)(3. 36) 2 = 0. 395? ?𝐸𝑓𝑖?𝑎?: 0. 5(0. 324)(0. 726) 2 = 0. 09? (0. 395 − 0. 09)/0. 395 * 100 = 77. 2% 4. Where does the energy go and how is it transferred? The energy loss turned into heat when transferred from ball to pendulum Questions 1. This question is from the Colorado State Driver’s license exam: A car at 30 miles per hour skids 40 feet with locked brakes. How far will the car skid with locked brakes at 90 miles per hour? (Hint: Think about Kinetic Energy). 360 feet because the mass is squared in the equation and it is tripled in the question therefore the skid distance would be triple squared so 40 x 3 x 3 = 360 2
PHYSICS 195L LAB REPORT - LAB 8: BALLISTIC PENDULUM 2. Suppose that you and two friends are discussing the design of a roller coaster. One friend says that each summit must be lower than the previous one. Your other friend says this is nonsense, for as long as the first one is the highest it doesn’t matter what height the others are. Explain which one is correct and why. (Assume no energy losses due to friction or air resistance). As long as the first summit is the highest the rest of them can be however tall or short they want. 3. When a jet plane lands on the deck of a carrier, is this an elastic or an inelastic “collision”? In this “collision” the before is just before landing and the after is after the plane has come to a stop. This is an inelastic collision because they move as one after the jet lands. 4. In the measurement of velocity by the free-flight method, what would be the effect on the measurements if (a) the front of the launcher were lower than the rear? (b) the distance between the photogates was long enough to let the ball drop 1 cm between the photogates? If the front was lower then it will have a higher exit velocity due to acceleration due to gravity. The final velocity would also increase. 3
