Final answer:
The distance in the lab experiment on projectile motion can be predicted using the time of flight and the initial velocity.
Step-by-step explanation:
In the lab experiment on projectile motion using photogates and time of flight pad, the distance can be predicted by measuring the time of flight and using the equation of motion for projectile motion. The equation for the distance traveled by a projectile is given by d = v0 * t, where d is the distance, v0 is the initial velocity, and t is the time of flight. By measuring the time of flight using the photogates and knowing the initial velocity, you can calculate the predicted distance.
