3. A projectile is fired from point 0 at the edge of a cliff, with initial velocity components of v0x= 60 m/s and voy = 175 m/s, as shown in the figure. The projectile rises and then falls into the sea at point P. The time of flight (total traveled time) of the projectile is 40.0 s, and it experiences no appreciable air resistance in flight. y Vo X P D> a) What is the angle at which the projectile was initially fired? b) What is the magnitude of the velocity of the projectile 21.0 s after it is fired? c) What is the height of the cliff? d) What is the distance D that the projectile travels in the horizontal direction?
