(a) If the height of the building is 20.0 m
A ball A is thrown straight up from the edge of the roof of a building. Another ball B is dropped from the roof 1.00 s later. You may ignore air resistance, (a) If the height of the building is 20.0 m, what must the initial speed of ball A be if both are to hit the ground at the same time? (b) On the same graph, sketch the position and velocity of each ball as a function of time, measured from when the first ball is thrown and taken origin at the ground.
