How fast is the bus traveling at this point? (e) If the student 's top speed is 3.5 m/s, will she catch the bus? (f) What is the mini- mum speed the student must have to just catch up with the bus? For what time and what distance does she have to run in that case? 2.89A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof 1.00 s later Ignore air resistance. (a) If the height of the building is 20.0 m, what must the initial speed of the first ball be if both are to hit the ground at the same time? On the same graph, sketch the positions of both balls as a function of time, measured from when the first ball is thrown. 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. (b) What must the height of the building be for both balls to reach the ground at the same time if (i) vo is
