Unformatted text preview: —*— I Assuming air resistance to he negligihte, the only acceleration on a projectile in flight is due to gravity: 3 = ”'3. The acceleration due to gravity only affects the vertical component of the velocity. The horizontal component is constant for the entire trajectory. I The key to many projectile motion problems is knowing that the vertical velocity is zero at the peak. knovvi ng the initial vertical component of the velocity and the acceleration due to to gravity [1i] mist {9.3 mist”, we can determine how long it takes the projectile to reach the peak. The time needed by gravityr to deplete the initial vertical velocity to zero is the time to the peak, rP. = i 1’ at How, it is a simple matter to find the height of the peak using the time to reach the peak, rF, in the formula 3;: v”: — £31: and the range using the formula .1: = v1.1: [the time to land is exactly double the time to reach the peak}.

    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.
