Suppose that a projectile is fired at an angle of 45[tex]\circ[/tex] from the(adsbygoogle = window.adsbygoogle || []).push({});

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?
