The highest barrier that a cannonball can clear is H,
when it is launched at an angle of 36 degrees above the ground. But
the cannon is itself on a hill that is sloped at an angle 10 above
the horizon. The cannon is of a given size so that its launch speed
of the cannonball is 92 m/s. A forward observer is posted to a hill
with an altitude of 200 m. What is the maximum height H that the
cannon will reach ? ( gravitational acceleration on earth is 9.8
m/s2. ) You may give the answer to 0 decimal places
