Unformatted text preview: Name Problem C (24 Points) A hydrogen atom moving at +5.0 x 10° i m/s collided with a helium atom initially at rest. After the collision, the velocity of the hydrogen atom was —3.0 x 106 l m/s. For this problem, we will assume that the mass of a helium atom is exactly four times the mass of a hydrogen atom (to make the calculations easier) and we will neglect all external forces during the collision. Was the collision elastic? Explain your answer in a few sentences supported by calculations. initial 0 —> +5.0x105m/s Q H He final —3.0xlo°m/s <— 0 —> ? H He ...

    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.
