Name: _____________________ Period:________ Date:___________________ <<< Conservation of Momentum: In-Class Problem Solving #1 >>> Problem 1 – Part A A 0.25kg red cart collides with a 0.50kg blue cart. The velocity of the red cart before the collision is 8 m/s. The velocity of the blue cart before the collision is -2 m/s. The velocity of the red cart after the collision is -2 m/s. What is the velocity of the blue cart after the collision? (Assume the track is frictionless and that the collision is perfectly elastic.) Problem 1 – Part B The carts are going in opposite directions before the collision. Are they still going in opposite directions after the collision? Explain your reasoning. Problem 2 – Part A A green cart collides perfectly elastically with a yellow cart. The green cart has a mass of 5 kg and the yellow cart has a mass of 8 kg. The green cart’s initial velocity is 10 m/s. If the final velocity of the green cart is 4 m/s and the final velocity of the yellow cart is 2 m/s, what is the initial velocity of the yellow cart?

    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.
