I have to do a physics project where we pick a scene from a movie and decide whether the physics used were good or bad.I chose the scene in Get Him to the Greek where a character falls into a pool but
A baseball leaves the bat at a speed of 105ft/s at an angle of 37degrees with the horizontal.-Distance ball travels (no air resistance = velocity^2 x sine (2 x angle)/g = 105^2 x sine 74/32.2
