A projectile is fired from a cliff 180 feet above the water at an inclination of 45° to the horizontal, with a muzzle velocity of 70 feet per second. The heighth of the projectile above the water is given by
- 32x²
h(x) = + x + 180
(70)
where x is the horizontal distance of the projectile from the face of the cliff. Use this information to answer the following
