A trebuchet located at (0, 0, 0) launches a projectile from level ground with initial velocity (1, 10, 25). A wind is blowing which applies a constant acceleration of 2 m/s² in the positive x-direction. A very tall castle wall which is located along the plane y = 20. How high is the projectile above the ground when it reaches the wall? Use -10 m/s² in the z-direction for acceleration due to gravity. A. The projectile hits the ground before it reaches the wall. B. The projectile is 20 m above the ground when it reaches the wall. C. The projectile is 24 m above the ground when it reaches the wall. D. The projectile is 30 m above the ground when it reaches the wall. E. The projectile is 125 m above the ground when it reaches the wall.
