Thank you so much for your help! I was having trouble with those first couple steps, I really appreciate you breaking it down for me. You're great! :)

And now I construct a right triangle to find the complete velocity and solve for theta to give me the angle?

That would make it 10.897 m/s.

The horizontal velocity would need to be 14.71 m/s then?

It would take 1.56 seconds i believe.

I graphed a generic polynomial like Ax^2 +Bx+C, and since I know the A value is -4.9 I plugged that in, and I know that the object is starting from the ground so I made C equal to 0 and I just played with the value of B until I got 12 meters in height. I'm sorry if I'm being difficult, my...

Whoops i mistyped. I meant 15.33, but that was the lowest value I found that could give a maximum vertical height of 12 meters.

My apologies. Wouldn't the initial vertical velocity have to be about 3.33? I could do the problem given either a velocity or an angle but I am extremely lost on how to do it without both. Thanks!

Homework Statement You are an invading army who wants to launch a rock over the enemy castle’s wall. The wall is 12 meters high and there is a moat surrounding the wall which forces you to launch from a distance of 17 meters away. What angle and velocity should you shoot at in order to just...
