need clear directions and answer
A mortar* crew is positioned near the top of a steep nill. 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 = 49.0degree (as shown), the crew fires the shell at a muzzle velocity of 256 feet per second. How far down the hill does the shell strike if the hill subtends an angle Greek Phi = 39.0degree from the 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?Explanation / Answer
No diagram. Trajectory eqn:
y = h + x
