1 Chapter 7 Linear Momentum 4. A 30.00 kg mass falls from a height of 4.000 m. The momentum of the mass just before it hits the ground is: A. 144.2 kg m/s. B. 187.8 kg m/s. C. 320.0 kg m/s. D. 442.4 kg m/s. E. 502.1 kg m/s. 5. A 3.000 kg ball is pitched with a kinetic energy of 20.00 Joules. Then the momentum of the ball is: 6. If the momentum of a ball is doubled, then the kinetic energy is: 8. A 4.00 kg ball is traveling at 5.00 m/s and strikes a wall. The 4.00 kg ball bounces off the wall with a velocity of 4.0 m/s. The magnitude of the change in momentum of the ball is:

    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.
