1. The problem statement, all variables and given/known data King Arthur's knights use a catapult to launch a rock from their vantage point on top of the castle wall, 12m above the moat. The rock is launched at a speed of 27m/s and an angle of 39∘ above the horizontal. How far from the castle wall does the launched rock hit the ground? 2. Relevant equations sin(theta) cos(theta) x=1/2at^2 3. The attempt at a solution I found the Vy and Vx components. To find time you see how long it reaches to the peak so I divided Vy/10? I found out time was t=1.69s (probably wrong) Then right there I'm stuck. I don't know what to do with the 12m either. I think I'm on the right track but maybe I'm just wrong.
