A golf ball is thrown straight up from the edge of the roof of a building. A second golf ball is dropped from the roof a time of 1.02 s later. You may ignore Part A air resistance. If the height of the building is 20.9 m , what must the initial speed be of the first ball if both are to hit the ground at the same time? v = 8.34 m/s Submit Previous Answers v Correct Part B Consider the same situation, but now let the initial speed vo of the first ball be given and treat the height h of the building as an unknown. What must the height of the building be for both balls to reach the ground at the same time for vo = 9.00 m/s. h = 4.386
