Provide an appropriate response.A human cannonball is to be fired with an initial speed of 80 ft/sec. The circus performer hopes to land on a cushion located 190 feet downrange at the same height as the muzzle of the cannon. The circus is being held in a large room with a flat ceiling 33 feet higher than the muzzle. Can the performer be fired to the cushion without striking the ceiling? If so, what is the proper firing angle? (g = 32 ft/sec2)
What will be an ideal response?
No: firing angle = 35.9° under these conditions.
