Ball Dropped from the mast of a moving ship as a projectile Where would a ball dropped from the mast of a moving ship land? (Assume that the ship’s velocity is constant and air resistance is negligible.)

Air Drop as a Projectile What would happen to a package dropped from a moving airplane, if air resistance was negligible? http://www.physicsclassroom.com/mmedia/v ectors/pap.cfm

Facts and Concepts for Type I Horizontally launched voy= 0 ax = 0 ay = 9.8 m/s/s downward (-9.8m/s/s) Trajectory (path) is one side of an upside down parabola Vertical displacement (Dy) is neg. (downward) Impact velocity is faster than launch velocity, and angle of impact is below the horizon (negative in the Cartesian coordinate plane)
