A cow, with a mass of 327 kg, if fired from a medieval catapault, and travels a horizontal distance of 1375 m. It lands in a depression 39 m below its starting position. If it is launched at an angle of 37.0above the horizontal, find its initial speed.

Thank you very much!
What I did for here was make a equation for time of flight
dx=v1*cos37* t +1/2 at^2
1375=v1x*cos37*t
\Delta t= 1372/v1*cos37
now that i have \Delta t I have inserted it into my vertical equation so
dy=v1y*cos37* t +1/2 at^2
-39=v1*sin37*(1372/v1*cos37) + 1/2...
I am sorry, after I posted this I realized that this would do nothing. I just tried something because I was running out of ideas. My only other idea would be to use this equation for y as max height for v2y is 0 m/s. (Correct me if this is wrong)
v1y^2 = v_0^2 + 2 a \Delta x
but...
