Solve each part of given problem:
Problem: At a Washington Nationals game, Jason Werth hits a baseball directly upward. You observe it takes 3.5 s for the ball to reach the top of its trajectory.
Part A: Find the ball's initial velocity?
Part B: Find the maximum height it reaches?
It'd be really helpful if you could show all steps of your work.
