Unformatted text preview: LAB 111 : P rojectile Motion Phys 111A021 Mario DeLaPaz September 29, 2010 Kui Chen Objective : Part 1. 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 2. To measure the range of a projectile leaving table at (measured) angle, and then use this table to predict where the projectile will strike the floor. Theoretical background: Part I. The motion of a projectile is a 2dimensional motion. In the xdirection, acceleration a x =0 velocity v x = constant . In the y direction, a y =g directed downwards. Distance = y. 1.) Y = gt 2 2.) X = v o Part I I. If the coordinate axes are chosen such that the origin is at the initial location of the projectile and the +y direction points upward, the following expressions hold for the projectile. 1.) V x = v cos 2.) V y =v sin gt 3.) X=v 0x t=(vcos )t 4.) Y= v 0y t gt 2 = (vsin )t gt 2 Equipment List : Projectile apparatus Steel ball...
