A high-powered 7-mm Remington magnum rifle fires a bullct with a velocity of 900 m/s on a rific
range. Neglect air resistance. (a) Calculate the distance such a bullet will drop at a range of 200 m when
fired horizontally. (b) To compensate for the drop of the bullet, when the telescope sight is pointed right at
the target, the barrel of the gun is aligned to be slanted slightly upward, pointed a distance above the
target. The downward fell due to gravity then makes the bullet strike the target as desired Suppose,
however, such a ne is fired uphill at a target 200 m distant. If the upward slope of the hill is 45", should
you aim above or below the target, and by how much? What should you do when shooting on a downhill
slope at 45° below horizontal?
