PART II. 1. Ball moving upward Remember that pulling causes acceleration (a) decreasing in speed as it is pulled downward (b) velocity is directed upward (c) acceleration is downward since it is being pulled downward (d) acceleration is in the - y direction (downward). (e) velocity is in the + y direction (upward). (f) ball moves slower on its way up. (Pull is in di- rection opposite to velocity and changes speed by decreasing it.) 2. Ball at maximum height (a) velocity is zero; ball has stopped.

    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.
