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

explanation:

its math

nah.   i'm just sleepy.

a displacement distance is size of displ

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
