Plug the photogate closest to the launcher into Digital Input 1 on the 850 Universal Interface. Plug the other photogate into Digital Input 2. The second photogate is located at a distance of 0. I'm away from the first photogate (The program calculates the initial speed by assuming the photogates are separated by 10.0 em and dividing by the time the ball takes to travel between the two gates ). 2. Plug the Time of Flight Accessory into Digital Input 3. 3. Place the projectile launcher close to your computer screen. Make sure a distance of about a meter is clear on the table/floor in the direction the ball will be fired. 4. Using the attached plumb bob, adjust the angle of the launcher to (" launched horizontally from a height above the table). 5. Make sure to align the photogates' beam hole with the ball. 6- Check to see that there is no one down range! Launch ling straight upward on the string. Don't jerk. Observe where the ball hits the table. Tape a small piece of tape to the table to mark the spot. Tape a sheet of blank paper at the location where the ball landed.

Will the Time of Flight for the two click position (horizontal fire) be more than, less than, or the same as the Time of Flight for the three click position? Explain your logic! 2. Did the time of flight depend on the initial horizontal speed? What does this imply about the dependence of the vertical motion on the horizontal motion? 3. How well did your predicted range compare to the actual range? What does this show? L 4. How would the horizontal range change if the muzzle velocity was doubled? Explain how you know. 5. How would the horizontal range change if the height from the ground was doubled? Explain how you know. 6. How would the horizontal range change if the mass of the ball was doubled?
