1. A projectile is fired from the edge of a cliff with initial velocity components of v0x = 60.0 m/s and v0y = 175 m/s. The projectile rises and then falls into the sea below the cliff. The time of the flight of the projectile is 40.0 s and there is no air resistance. a. At what angle is the projectile fired? b. What is the magnitude of the projectile 20.0 s after it is fired? c. What is the height of the cliff? d. How far from the cliff does the projectile hit the sea surface?
