Part II: Measuring Range Values as a Function of the Launch Angle θFigure Fourvo′ho′xRθo7.)Place the launcher on the floor. Point the launcher toward your assigned "alleyway."8.)The launcher needs toon the sideof the vertical face that does not have the overhangMake sure the launcher is on this side and in the set of slots that will allow you to change the angle of the launch without changing the vertical height from which the ball is launched.9.) Tilt the launcher so that it is inclined 5°to the horizontal. Next, measure the vertical height ′ho, with respect to the floor, of the point on the barrel of the launcher where the projectile loses contact with the launching mechanism. Record this value on the data sheet. (Note:as we increase the tilt of the launcher, we want to keep this vertical distance the same!)10.)Load the launcher and, when it is safe to do so, fire the projectile making sure to carefully note were it strikes the floor. Fix a piece of paper over a piece of carbon paper on the spot noted.Fire the projectile two timesfrom this angle. Measure the range value ′xRfor each trial and record the value on the data sheet. 11.)Repeat step ten, making sure to keep ′hoconstant, for the following angles:10°,20°,25°,30°,35°,40°,45°,50°,55°,60°,65°,75°,80°,and 85°Part III: Calculations12.)By now, you should have calculated an average initial speed for your projectile. In this experiment, if we assume the initial speed for the projectile is independent of the angle the launcher o. .
