A catapult on a cliff launches a large round rock towards a ship on the ocean below. The rock leaves the catapult from a height H of 33.0 m above sea level, directed at an angle above the horizontal with an unknown speed v0. The projectile remains in flight for 6.00 seconds and travels a horizontal distance D of 175 m. Assuming that air friction can be neglected, calculate the value of the angle (in degrees). To what height above sea level does the rock rise?
