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...

At a construction site, a 68.0 kg bucket of concrete hangs from
a light (but strong) cable that passes over a light friction-free
pulley and is connected to an 85.0 kg box on a horizontal roof (see
the figure (Figure 1)). The cable pulls horizontally on the box,
and a 47.0 kg bag of gravel rests on top of the box. The
coefficients of friction between the box and roof are shown. The
system is not moving.

A 28.0 kg block is connected to an empty 1.80 kg bucket by a cord running over a frictionless pulley. The coefficient of static friction between the table and the block is 0.41 and the coefficient of kinetic friction between the table and the block is 0.31. Sand is gradually added to the bucket until the system just begins to move Calculate the mass of sand added to the bucket. Express your answer using two significant figures.

Part A A mill in a textile plant uses the belt-and-pulley arrangement shown to transmit power. When t = 0 an electric motor is turning pulley A with an angular velocity of wa=5 rad/s. (Figure 1) If this pulley is subjected to a constant counterclockwise angular acceleration of a = 2 rad/s., determine the angular velocity of pulley B after B turns 3 revolutions. The hub at D is rigidly connected to pulley C and turns with it. Express your...
