A mortar is like a small cannon that launches shells at steep angles. 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 =53.0∘ (as shown), the crew fires the shell at a muzzle velocity of 183 ft/s.
How far down the hill does the shell strike if the hill subtends an angle =31.0∘ from the horizontal? Ignore air friction.
