Experiment 2: Predicting the Horizontal Distance
Traveled from a Launched Projectile
Purpose:
The purpose of this experiment is to use the time of flight and the
initial velocity to predict the horizontal distance traveled by a ball shot
off a table at an angle.
Theory:
A ball is launched off a table from a height h at an angle
θ above the
horizontal. The horizontal distance, x, traveled by the ball is given by
where
is the initial velocity of the ball and t is the time
of flight.
Setup:
1. Clamp the Projectile
Launcher to one end of
a sturdy table with the
launcher aimed away
from the table.
2. Adjust the angle of the
Projectile Launcher to
any desired angle.
Record the angle in
Table 2.1.
3. Attach the Photogate Mounting Bracket to the Launcher and
connect the Photogates to the computer interface.
Equipment required:
