An experiment is designed to determine the launch angle that will give a projectile the greatest range (make it go the longest d
istance). 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?
If the angle of the launcher is increased, the rock will go further.
Changing the angle of the launcher will vary the distance that the rock can be projected.
if angle is increased, rock will go further if the angle starts at 0, then increases to 90 degrees (straight up) the rock will go up then bounce off of the launcher going either front or back, but vastly shorter than if it were pointed straight ahead
2nd one changing angle change the distance we see that is true
