In 2004 baseball player Adam Dunn hit the longest home run ever hit in Great American Ballpark in Cincinnati. He hit a homer which went 535 ft (163.1 m). In the following parts ignore any effects due to air resistance and assume the baseball lands at the same height it was hit.
Part A If he hit the ball at an angle of 55 degrees, what was the initial velocity of the baseball?
Part B How long was the ball in the air?
Part C What was the maximum height achieved by the baseball?
