Question: In the absence of air resistance, a projectile is launched from and returns to ground level. It follows a trajectory similar to that shown in the figure below and has a range of 25 m. Suppose the launch speed is doubled, and the projectile is fired at the same angle above the ground. What is the new range? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
