An experiment is designed to determine the launch angle that will give a projectile the greatest range (make it go the longest distance).. The "launcher" is a slingshot type of apparatus that is spring-loaded and released by a trigger. For
each trial, the same painted rock is retrieved and launched. Measurements are taken linearly from the launch site to the
landing site. The trials were done on a windless day.
Which of the following would be a good hypothesis for this experiment?
