Worksheet 4: Two-dimensional motion II (Projectile motion) Questions 1. Pendulum Swinging In the first picture, it drops straight downwards. In the second picture, it mostly falls downwards, but also has some initial ve- locity to the right. (the initial velocity vector is tangent to the path of the pendulum). The third positoin has an initial velocity that’s horizontal to the right. It begins moving to the right and then falls under the influence of gravity. The fourth one begins to move up and to the right before falling under the influence of gravity. The fifth one falls straight down, just like the first picture. 2. Throwing an object from atop a cliff You will send the shot farther if you shoot at an angle shallower than 45 o . Throwing an object from the cliff essentially gives the ball more time in the air, hence having more horizontal velocity (while sacrificing some height) will cause the ball to go further.

    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.
