(7) A cannon launches a cannonball 30 above the horizontal, 100 ft above its target, and with an initial speed of 600 ft/sec. Use the g = 32 ft/sec for the constant of acceleration due to gravity. Answer the following: a. How long is the cannonball in the air before it lands? b. How far does it travel horizontally? c. What is the maximum height achieved? v = 600 ft/sec h = 100 ft Maximum height = ? X = ? Total time = ?
