Suppose that a projectile is fired at an angle of 45[tex]\circ[/tex] from the
horizontal. Its initial position is the origin in the xy-plane, and its
initial velocity is 100[tex]\sqrt{}2[/tex] ft / sec. Then its trajectory will be the part of
the parabola y = x -( [tex]\frac{}{}x/[/tex]25)^2 for which y ≥ 0.
a) How far does the projectile travel (horizontally) before it hits the
ground?
b) What is the maximum height above the ground that the
projectile attains?
