A projectile is fired from point0 at the edge of a cliff, with an initial speed of v0 = 50.0 m/s in the direction of 40° above the horizon, as shown in the figure. The projectile rises and then falls into the sea at pointP. The time of flight of the projectile is 15.0 s, and it experiences no appreciable air resistance in flight. What is the height of the cliff?
