Wile E. Coyote is so desperate to catch the Roadrunner that he built himself a catapult to use on those darn vertical cliffs he is always running into. He figures he will need it to shoot him meters straight up. How fast must the catapult propel him upwards to reach that height? (Use m/sec for the acceleration due to gravity. As you know, Cartoonland has a different gravitational constant, allowing cartoon characters to fall from great heights without being injured. Do not try this at home.)  

initial acceleration
initial velocity
initial position

Notice that the question is asking, 'how fast?'.
Be mindful of units.
