A brick lies perilously close to the edge of the flat roof of a building. The roof edge is 50 ft above street level, and the brick has 540.0 J of potential energy with respect to street level. Brick Someone edges the brick off the roof, and it begins to fall. What is the brick's kineticenergy when it is 35 ft above street level? Part 2 See Hir What is the brick's kinetic energy the instant before it hits the street surface?
