Step 1
Step 1: The range of a projectile is given by the formula: $$R = \frac{v_0^2 \sin(2\theta)}{g}$$ where $v_0$ is the initial velocity, $\theta$ is the launch angle, and $g$ is the acceleration due to gravity. Show more…

Two projectiles are launched with a speed of 100m/s. The angle of elevation of the first projectile is 30°, and that of the second is 60°, both with respect to a horizontal surface. Which of the following observations is FALSE? A. Both projectiles have the same acceleration in their movement B. Both projectiles have the same range on the horizontal surface C. The flight time of the first projectile is less than that of the second D. Both projectiles have the same speed when they hit the ground E. Both projectiles have the same flight time when they hit the ground
