.. 10.17 A 12.0-kg box resting on a horizontal, frictionless surface is attached to a 5.00-kg weight by a thin, light wire that passes over a frictionless pulley (Fig. E10.17). The pulley has the shape of a uni- form solid disk of mass 2.00 kg and diameter 0.500 m. After the sys- tem is released, find (a) the tension in the wire on both sides of the pulley, (b) the acceleration of the box, and (c) the horizontal and ver- tical components of the force that the axle exerts on the pulley.

A hollow cylinder that is rolling without slipping is given a velocity of 5.0 m/s and rolls up an incline to a vertical height of 1.0 m. If a hollow sphere of the same mass and radius is given the same initial velocity how high vertically does it roll up the incline?
•• A squirrel-proof bird feeder has a lever that closes to protect theseeds when a 0.42-kg squirrel sits on it, but not when a 0.077-kgbird perches there. (a) If the lever radius is 9.6 cm, what torquesdo the squirrel and the bird each exert on it? (b) The torque produced by the animal is balanced by a spring that applies a perpendicular force a distance of 3.5 cm from the axis of rotation. Ifthe squirrel must stretch the spring 2.5 cm in order to close thelever and protect the seeds, what should be the force constant ofthe spring

A weight with mass ?w=250 g is tied to a piece of thread wrapped around a spool, which is suspended in such a way that it can rotate freely. When the weight is released, it accelerates toward the floor as the thread unwinds. Assume that the spool can be treated as a uniform solid cylinder of radius ?=4.00 cm and mass ?s=100 g. Find the magnitude of the acceleration of the weight as it descends. Assume the thread has negligible mass and does not slip or stretch as it unwinds. Find the tension in the thread.
If a force vector of F=40i-20j (N) is acted on an object at a distance of r=2i+3j (m) from the axis of rotation, then what is the moment of inertia? (The angular acceleration is 11rad/s2 by using the magnitude of torque provided by the force.)
