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= 50.0 degress, the crew fires the shell at a muzzle velocity of 226 feet per second. How far down the hill does the shell strike if the hill subtends an angle Phi=34 degrees, from the horizontal?
How long will the mortar shell remain in the air?
How fast will the shell be traveling when it hits the ground?
