Consider two objects with m1 m2 connected by a light string that passes over a pulley having a moment of inertia of I about its axis of rotation as shown in Figure P10.44. The string does not slip on the pulley or stretch. The pulley turns without friction. The two objects are released from rest separated by a vertical distance 2h. (a) Use the principle of conservation of energy to find the translational speeds of the objects as they pass each other. (b) Find the angular speed of the pulley at this time.
A uniform cylindrical grinding wheel of mass 50.0 kg and diameter 1.0 m is turned on by an electric motor. The friction in the bearings is negligible.

What torque must be supplied by the motor to keep the wheel rotating at a constant angular velocity?
An electric motor turns a flywheel through a drive belt that joins a pulley on the motor and a pulley that is rigidly attached to the flywheel as shown in Figure P10.37. The flywheel is a solid disk with a mass of 80.0 kg and a radius R = 0.625 m. It turns on a frictionless axle. Its pulley has much smaller mass and a radius of r = 0.230 m. The tension Tu in the upper (taut) segment of the belt is 135 N, and the flywheel has a clockwise angular acceleration of 1.67 rad/s2. Find the tension in the lower (slack) segment of the belt.

The reel shown in Figure P10.71 has radius R and moment of inertia I. One end of the block of mass m is connected to a spring of force constant k, and the other end is fastened to a cord wrapped around the reel. The reel axle and the incline are frictionless. The reel is wound counterclockwise so that the spring stretches a distance d from its unstretched position and the reel is then released from rest. Find the angular speed of the reel when the spring is again unstretched. Figure P10.71
A solid sphere and a hollow cylinder of the same mass and radius have a rolling race down an incline as in Example 13.9 (page 372). They start at rest on an incline at a height h above a horizontal plane. The race then continues along the horizontal plane. The coefficient of rolling friction between each rolling object and the surface is the same. Which object rolls the farthest? (Justify your answer with an algebraic expression.) 72. Conservation of energy provides a very simple approach to this problem. Each object starts at rest on the incline, and each object stops on the horizontal surface. Along the way there is an increase in thermal energy between the surface and the object. Lets include the Earth, the rolling object, and the surface in the system. We set the reference configuration to the horizontal surface. We can create an energy bar chart as weve done Chapter 13 - Rotation II: A Conservation Approach13-44 previously to see that the initial gravitational potential energy is eventually dissipated as thermal energy as the object rolls a total distance S. Ugi=Eth mgh=rFNS S=mghrFN Each object has the same mass m, is released from the same height h, and has the same coefficient of rolling friction r with the surface. The normal force exerted by the surfaces on the each object is also the same since the objects have the same mass. So, S is the same for both objects. In other_words, they travel the same distance from the starting point. This result may be surprising, but it is not a race in the traditional sense. We didnt ask which object arrived at the finish line first. Instead, we asked where the finish line is. The sphere gets there sooner because it has a small rotational inertia, so it rolls down the incline at a higher speed. Figure P13.72ANS
A war-wolf, or trebuchet, is a device used during the Middle Ages to throw rocks at castles and now sometimes used to fling large vegetables and pianos as a sport. A simple trebuchet is shown in Figure P10.19. Model it as a stiff rod of negligible mass, 3.00 m long, joining particles of mass m1 = 0.120 kg and m2 = 60.0 kg at its ends. It can turn on a frictionless, horizontal axle perpendicular to the rod and 14.0 cm from the large-mass particle. The operator releases the trebuchet from rest in a horizontal orientation. (a) Find the maximum speed that the small-mass object attains. (b) While the small-mass object is gaining speed, does it move with constant acceleration? (c) Does it move with constant tangential acceleration? (d) Does the trebuchet move with constant angular acceleration? (e) Does it have constant momentum? (f) Does the trebuchetEarth system have constant mechanical energy?
