Question

A brick is dropped (zero initial speed) from the roof of a building. The brick strikes the ground in 2.10 s. You may ignore air resistance, so the brick is in free fall. a) How tall, in meters, is the building? (b) What is the magnitude of the bricks velocity just before it reaches the ground? m/s (e) Sketch ay t, vy t, and yt graphs for the motion of the brick. (Do this on paper, Your instructor may ask you to turn in these graphs.)
