Physics 1050 Experiment 5 Prelab Questions These questions need to be completed before entering the lab. Please show all workings. One cart is pushed towards another stationary cart. They collide, stick, and move together. Prelab 1: Write the equation for the total momentum before the collision. Write the equation for the total momentum after the collision. Prelab 2: Do you expect v f to be greater than v 1 or less than v 1 ? Explain why. Prelab 3: If m 1 = 0.500 ± 0.005 kg, m 2 = 1.000 ± 0.005 kg, v 1 = 0.25 ± 0.01 m/s, and v f = 0.07 ± 0.01 m/s, calculate the initial and final momentum and the impulse. Include uncertainty with each calculation. initial final v 2 = 0 v 1 v f m 1 m 2 m 1 m 2

Physics 1050 Experiment 5 Part I: Introduction In this experiment, you will test conservation of momentum by determining the momentum before and after a collision between two carts and comparing the values. You will also study the relationship between force and momentum by examining the change in momentum of a cart due to force exerted on it by an elastic band. Impulse, , is defined as the change in momentum of an object. Impulse is a vector quantity. Impulse is also given as the integral of force over time p f = p i r I = " p = p f # p i r I = F d t " . I

    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.
