A mortar crew is positioned near the top of a steep hill. Enemy forces are charging up the hill and it is necessary for the crew to spring into action. Angling the mortar at an angle of theta= 67 degrees, the crew fires the shell at a muzzle velocity of 131 ft per second. How far down the hill does the shell strike if the hill subtends an angle 32 degrees from horizontal? (Ignore air friction.) How long will the mortar shell remain in the air? How fast will the shell be traveling when it hits the ground?
