you are firing projectile ground level point three times far away

a) You are firing a projectile from ground level at a point that is three times as far away as it is high. You want the projectile to follow a trajectory so that when it reaches the target, it is approaching horizontally. Show that the angle you must fire the projectile at is given by Tan(theta)= 2/3.


b) If h= 14.0 m, what must initial velocity equal (in meters/second) in the situation described above?
