When a projectile is launched at an initial height of h feet above the ground at an angle of a with the horizontal and the initial velocity is Vo feet per second, the path of the projectile is modeled by the
parametric equations
* = (v. cos et an
and y=h+(sin ) - 162
Joey hits a baseball 3.3 feet above ground with an initial velocity of 125 feet/second at an 28° angle
with the horizontal.
Write the parametric equations that model this situation and use your equations to algebraically
solve the following question. DO NOT round any values until your final answer.
. Will the ball clear an 8-foot wall that is 380 feet away from Joey? Mathematically justify
your answer and give the actual height of the ball at this location (to one decimal palace)
