A mortar* crew is positioned near the top of a steep hill. Enemyforces are charging up the hill and it is necessary for the crew tospring into action. Angling the mortar at an angle of θ = 57.0o (asshown), the crew fires the shell at a muzzle velocity of 241 feetper second. How far down the hill does the shell strike if the hillsubtends an angle φ = 36.0o from the horizontal? (Ignore airfriction.)
How long will the mortar shell remain in the air?
How fast will the shell be traveling when it hits theground?
