bracket. Plug the Photogate into Channel 1 on the computer
interface.
4. Connect the Time-of-Flight Accessory to the computer interface.
Use the extender cable if necessary.
5. Run the timing program and set it to measure the time between
blocking of two Photogates (one Photogate and the timer plate of
the Time-of-Flight Accessory).
6. Set up the vertical target board about 0.5 m in front of the Projectile
Launcher. Use the Plumb Bob to aid with the measurement of the
exact distance between the muzzle of the launcher and the timer
plate. Record the distance in Table 3.1.
Procedure:
1. Load and cock the launcher to the long range position.
2. Fire a test shot to see where the ball hits the vertical target. Hold
the timer plate against the vertical board at the place where the ball
hit.
3. Shoot the ball again and record the time of flight in Table 3.1.
4. Move the vertical target to 1 m, 1.5 m, and 2 m in succession,
finding the time of flight for each position and recording in Table
3.1.
Analysis
1. Calculate the horizontal velocity for each position. Is the velocity
constant?
