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 = 32.0 m above sea level, directed at an angle theta = 49.3° above the horizontal, and with a speed v = 25.8 m/s. Assuming that air friction can be neglected, calculate the horizontal distance D traveled by the projectile.

im not sure what formula to use to find time
