3. A bucket at for collecting water from a well is suspended from a light rope that is wrapped around a pulley with radius r = 10 cm and a moment of inertia of 0.1 kg-m². The empty bucket has a mass of 2 kg. Suppose someone drops the bucket from rest. Use conservation of energy to find how fast the bucket moving right before it hits the surface of the water 3 m below. 10 Note: you need to use that the speed of the bucket, v, is related to the angular speed of the pulley, w, by v = rw. Justify this with a brief explanation.

The spin cycle of a clothes washer extracts the water in clothing by greatly increasing the water’s apparent weight so that it is efficiently squeezed through the clothes and out the holes in the drum. In a top loader’s spin cycle, the 45-cm-diameter drum spins at 1200 rpm around a vertical axis. What is the apparent weight of a 1.0 g drop of water?

Q9 A Physics teacher is teaching a class about the effect of friction. They assemble a track that has a vertical loop of radius 30.0 cm. A toy car of mass 50.0 g is released from rest at a height of 1.00 m at the beginning of the track. The car rolls down the track and follows the loop before exiting the track. The teacher asks the class to calculate the speed of the toy car if the coefficient of friction were 0. Im 30 cm What is the calculated speed of the toy car as it reaches point X? (A) 1.49 ms (B) 2.21 ms! (C) 2.80 ms! (D) 7.84 ms

*Chapter 11, Problem 13 Nonuniform ball. In the figure, a ball of mass M and radius R rolls smoothly from rest down a ramp and onto a circular loop of radius 0.47 m. The initial height of the ball is h = 0.34 m. At the loop bottom, the magnitude of the normal force on the ball is 1.92Mg. The ball consists of an outer spherical shell (of a certain uniform density) that is glued to a central sphere (of a different uniform density). The rotational inertia of the ball can be expressed in the general form I = BMR², but B is not 0.4 as it is for a ball of uniform density. Determine B. the tolerance is +/-2%
