PHYS 1121 Exp. 6 2-D Collisions Homework NAME_________________________ 1. Find the x- and y-components of momentum of a 2.25-kg object moving at 3.70 m/s at an angle of 120.0 degrees with respect to the positive x-axis. 2. Between two collisions, how can you determine which one is more elastic? 3. In this experiment, the force of gravity clearly causes both the projectile and the target

Unformatted text preview: to accelerate. We still, however, use this situation as an example of a two-dimensional collision where conservation of momentum holds. Explain why this is the case. 4. For a two-dimensional elastic collision, two equations are required to express conservation of momentum, whereas only one equation is required to express conservation of kinetic energy. Explain why this is the case....

    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.

    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.
