A cannon that shoots projectiles at 100m/s must hit a target 400m away and 30m above the ground. What angle must the cannon point at in order to hit the target?
I have two functions:
x = V*cos(theta)*t, where V = initial velocity, and
y=V*sin(theta)*t - (g*t^2)/2 where g = gravity's acceleration
but i can't solve for theta.
can somebody help me?
