Determine the weight of your car. How does this compare to the slope of your graph? The mass of the car was 0.512 kilograms and my slope was 4.17. If you multiply the mass of the car by 10 it comes out to be 5.12, which is almost a difference of 1. 5. What accounts for the difference noted in #4? In my experiment there was a few experimental errors. First, we didn’t start the car at the same height, which affects the velocity of the cart. Second, on Logger Height (m) Trial 1 (m/s) Trial 2 (m/s) Trial 3 (m/s) Average (m/s) Mass (kg) Ek (Joules) Eg (Joules) 0.17 1.344 1.552 1.541 1.479 0.512 0.56 0.56 0.21 1.376 1.454 1.688 1.506 0.512 0.58 0.58 0.33 2.178 2.138 2.160 2.160 0.512 1.19 1.19 0.56 2.845 2.917 2.942 2.900 0.512 2.15 2.15

Pro we didn’t highlight the exact section of the car going down the ramp, which also affects the velocity. These are two accounts of the difference noted in #4. 6. Using the Mathematical Model discussed in class (Egg=mgh) determine the

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
