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 34.0m above sea level, directed at an angle above the horizontal with an unknown speed. The projectile remains in flight for 6.00 seconds and travels a horizontal distance of 174m. Assuming that air friction can be neglected, calculate the value of the angle (in degrees). Also calculate the speed at which the rock is launched.(adsbygoogle = window.adsbygoogle || []).push({});

My brains are cooked. I'm not sure where to begin with this one.
