A block (mass = 1.1 kg) is hanging from a massless cord that is wrapped around a pulley (moment of inertia = 1.2 x 103 kg-m2), as the figure shows. Initially the pulley is prevented from rotating and the block is stationary. Then, the pulley is allowed to rotate as the block falls. The cord does not slip relative to the pulley as the block falls. Assume that the radius of the cord around the pulley remains constant at a value of 0.042 m during the block's descent. Find (a) the angular acceleration of the pulley and (b) the tension in the cord.

A block of mass m1 = 2.05 kg and a block of mass m2 = 6.40 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg. The fixed, wedge-shaped ramp makes an angle of ? = 30.0° as shown in the figure. The coefficient of kinetic friction is 0.360 for both blocks.
A uniform disk of mass 7 kg and radius 0.2 m is free to rotated about an axis perpendicular to its center. A constant force of size 146 N acts at the edge of the disk, in a direction tangent to that edge. The force acts until the disk has completed 169 full rotations. What is the angular momentum of the disk after those rotations are complete, in kg m2/s? It could be useful to you to know that the rotational inertia of a uniform disk is 1/2 M R2. (Please answer to the fourth decimal place - i.e 14.3225)

A motorcycle with a 200 kg body has two 20 kg wheels with 40 cm radii (whose mass distribution is not known). At the top of a 10 m tall hill the wheels are spinning at 358 rpm, and after coasting down the hill the motorcycle is moving at 21 m/s. If the wheels of the motorcycle were not slipping the entire time, what is the moment of inertia of a single wheel?

A rope with a negligible mass has two blocks that are suspended over a pulley, m, and M, as shown in the image. The pulley can be considered as a uniform solid cylindrical disk. What is the equation for the net torque on the disc? Assume acceleration of blocks are a=(1/2)(9.8m/s2). What is the moment of inertia for this shape? (using the net torque equation from the above question, substitute the moment of inertia) The angular acceleration is correlated to the linear acceleration as α=r. Make the substitution into the torque equation in order to get the equation in terms of acceleration, α only.

A carousel has a radius of 1.70 m and a moment of inertia of 118 kg m2. A girl of mass 47.5 kg is standing at the edge of the carousel, which is rotating with an angular speed of 3.10 rad/s. Now the girl walks toward the center of the carousel and stops at a certain distance from the center d. The angular speed of the carousel is now 5.2 rad/s. How far from the center, in meters, did the girl stop?
A small 0.360-kg object moves on a frictionless horizontal table in a circular path of radius 3.00 m. The angular speed is 4.97 rad/s. The object is attached to a string of negligible mass that passes through a small hole in the table at the center of the circle. Someone under the table begins to pull the string downward to make the circle smaller. If the string will tolerate a tension of no more than 160 N, what is the radius of the smallest possible circle on which the object can move?

John McClane, desperately trying to escape the bad guys in an upper floor of a skyscraper, grabs a fire hose and crashes out a window. He falls toward the ground, dragging the hose with him. The hose is wound around a cylinder that has a moment of inertia equal to 5 kg m2, and the hose unspools from the cylinder as McClane falls. Assuming that the hose is pulled from the cylinder at an angle that is perpendicular to the cylinder's radius, what is McClane's acceleration? Let McClane's mass be 75 kg and the radius of the cylinder be 0.5 m. Neglect friction and air resistance. Hose Wall Spool McClane
