time of flight:
t=distance/speed=45.1m/(s*cosTheta) where s is the launch speed.
so you have not t in terms of theta.
time in air:
hf=hi+vi*sinTheta*t-4.9t^2 hf=hi=0
so put t in the equationi, you should be able to solve for theta. You may have to use a double angle formula if you dont remember, look it up.
William Tell must split the apple atop his son’s head from a distance of 45.1m. When William aims directly at the apple, the arrow is horizontal. At what angle must he aim it to hit the apple if the arrow travels at a speed of 45.956m/s
