Find the answer for all parts of given question:
Question: A ball is thrown straight up with an initial velocity v1. It takes time t1 to reach a maximum height of h1.
Part A: What is the time t2 for the ball to reach the maximum height?
Part B: What is the maximum height h2 if its initial velocity is doubled?
Please show all work and steps to find the maximum height h2 if its initial velocity is doubled and neglect air resistance.
