Q. A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof a time of 1.01 s later. You may ignore air resistance.

Part A : If the height of the building is 19.5 , what must the initial speed v0 be of the first ball if both are to hit the ground at the same time?

Part B : Consider the same situation, but now let the initial speed v0 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 v0 = 8.80 . ?

Part C : If is greater than some value v max , a value of h does not exist that allows both balls to hit the ground at the same time. Solve for vmax .

part D : If is less than some value , a value of does not exist that allows both balls to hit the ground at the same time. Solve for.
