Experiment 4. Projectile Motion 4.4 Preliminary Assignment 1) A student performs the projectile motion experiment and records the following values for the photogate velocity and the measured range of the projectile at an elevation angle of 0 = 30 with an initial elevation of Y. = 0.087m using a pair of photogates spaced D = 0.10m apart: Angle of Elevation: 0 = 30 Photogate Separation: D = 0.10 m Initial Elevation Y. = 0.087 m Vo Run ITOF y cal y meas max max Number (my/s) (m/s) (s) (m) (m 2.872 0.910 2.911 0.913 2.883 0.914 U A W N 2.912 0.915 2.874 0.906 cal max = meas S = Sucal Symcas = * max SX cal = SX meas max = A) Calculate the initial velocity (v. ) of the projectile for each of the five runs.
