< Part A An unmarked police car traveling a constant 95 km/h is passed by a speeder. Precisely 2.00 s after the speeder passes, the police officer steps on the accelerator. ' If the police car accelerates uniformly at 2.00 m/s and overtakes the speeder after accelerating for 6.00 s what was the speeder's speed? v = ? km/h 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 1.07 s later. You may ignore air resistance. Part A If the height of the building is 19.7 m, what must the initial speed be of the first ball if both are to hit the ground at the same time? H 000 v = Part B #] ? m/s 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 = 8.95 m/s. h = ? m
