Reference no: EM13710000

Question: 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 34.0 m above sea level, directed at an angle Î¸ above the horizontal with an unknown speed v0. The projectile remains in flight for 6.00 seconds and travels a horizontal distance D of 143.0 m.

Part A: Assuming that air friction can be neglected, calculate the value of the angle Î.

Part B: Calculate the speed at which the rock is launched.

Part C: To what height above sea level does the rock rise.

I need help to find the speed at which the rock is launched.
