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 45Ā° below horizontal?

An electron is ejected into a horizontal uniform eā field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the eā field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
