1200cos(theta) t=3000 t=3000/1200cos(theta) or 5/2cos(theta) so I plug into the j component 1200sin(theta)(3000/1200cos(theta))- 16(5/2cos(theta))^2 That's where I'm stuck. I'm really not sure where to go from here

A shot fired from a gun with a muzzle velocity of 1200 ft per second is to hit a target 3000 feet away. Determine the minimum angle of elevation of the gun? Ok so I know that r(t)= (vcos(theta) t)i +(vsin(theta) t +16t^2)j I tried to set vcos(theta)t =3000, solve for t, and plug into the j...
