3. A baseball is hit with an initial velocity of 70 ft/sec at an angle of 50 degrees. If the ball is hit at an initial height
2.5 ft.
a) Find the parametric equation that represents the baseball's position.
b) How long is the ball in the air?
c) How far from the home plate does the ball land?
4. Joe Mauer hits ball 3 feet off the ground at an initial angle of 40 degrees with an initial velocity of
115ft/sec. Will the ball clear a 8 foot fence that is 370 feet from the home plate? If so, by how much? If not,
where does the ball land/hit.
Yes, it will clear the fence by 23.1 ft
