To study the projectile motion and apply the linear motion equations to solve this two-dimensional problem; To predict where a target of given size should be placed in order to be hit by a projectile leaving a table in a horizontal direction (Part I); To measure the range of a projectile leaving table at (measured) angle, and then use this value to predict where the projectile will strike the floor (Part II). Theory: Equations to be examined 1. y = 1 2 gt 2 2. x = v o t 3. v x = v o cos ( θ ) 4. v y = v o sin ( θ )− ¿ 5. x = v ox t = v o cos ( θ ) t 6. y =v 0y t 1 2 gt 2 =( v o sin ( θ ) )t 1 2 gt 2 Whereas, v 0 is the initial velocity at time 0 (t = 0). x is the position in the horizontal direction of the object x 0 is the initial horizontal position of the object at time 0 (t = 0) g is the acceleration due to gravity or (-9.8m/s 2 ) y is the position in the vertical direction of the object y 0 is the initial vertical position of the object at time 0 (t = 0) t is the time in seconds θ is the angle in degrees above the horizontal Data:

    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.
