Question

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 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 is the dependent variable?
A-the angle of the launcher
B-the amount of wind
C-how the distance was measured
D-how far the rock went

Answer 1

d

Step-by-step explanation:

Answer 2

The dependent variable is the variable which is the result of the changing experimental variable. In this case, how far the rock went is a result of changing the angle of launch. Therefore, how far the rock went is the dependent variable.
