A 22.0 kg bucket of concrete is connected over a very light frictionless pulley to a 375 N box on the roof of a building as shown in the figure. There is no appreciable friction on the box, since it is on roller bearings. The box starts from rest. 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)? A. 3.28 m/s
B. 5.20 m/s
C. 4.67 m/s
D. 3.00 m/s
