Problem 5.23 At a construction site, a 15.0-kg bucket of concrete is connected over a very light frictionless pulley to a 375-N box on the roof of a building. (Figure 1) There is no appreciable friction on the box, since it is on roller bearings. The box starts from rest. Part D How fast is the bucket moving after it has fallen 1.50 m (assuming that the box has not yet reached the edge of the roof)? Express your answer...
