8.31. Set Up: For an elastic collision with B initially stationary, the final velocities are and Apply these equations with and Solve: (a) The 0.300 kg glider moves to the right at and the 0.150 kg glider moves to the right at (b) Reflect: The relative velocity after the collision has magnitude the same as before the collision. The initial kinetic energy of the system is The final kinetic energy is the same as the initial kinetic energy, apart from a slight difference due to rounding. 8.32. Set Up: For an elastic collision with B initially stationary, the final velocity of B is Apply this equation with and Solve: Collision: Motion after the collision: The kinetic energy of the fixture just after the collision is converted to gravitational poten- tial energy as the fixture swings up to a maximum height h . Conservation of energy gives and 8.33. Set Up: For an elastic collision with B initially stationary, the final velocities are and Apply these equations with and Solve: (a) The proton recoils to the left at

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.
