A uniform, hollow, cylindrical spool has inside radius R/2, outside radius R, and mass M(Fig. P10.47). It is mounted so that it rotates on a fixed, horizontal axle. A counterweight of mass m is connected to the end of a string wound around the spool. The counterweight falls from rest at t= 0 to a position y at time t.

A uniform disk with radius R = [R} m and mass [M} kg rotates in a horizontal plane on a frictionless vertical axle that passes through the center of the disk. The angle through which the disk has turned varies with time according to 0(t) =1.4t + 6.9t2 rads. What is the angular velocity(rad/s) of a point on the rim of the disk at the instant after 1.2 rev.
The figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.5 cm and a mass of 24 grams and is initially at rest. Starting at time t = 0, two forces are to be applied tangentially to the rim as indicated, so that at time t = 1.2 s the disk has an angular velocity of 260 rad/s counterclockwise. Force F1 has a magnitude of 0.0988 N. What is magnitude F2? Number .164 Units N
A uniform disk with radius R = [R} m and mass [M} kg rotates in a horizontal plane on a frictionless vertical axle that passes through the center of the disk. The angle through which the disk has turned varies with time according to 0(t) =3.4t + 1.1t³ rads. What is the angular acceleration (rad/s?) of a point on the rim of the disk at the instant after 1.1 s.
A box of mass 1.49 kg connected to a pulley with a string is pulled by a force F= 114 newtons that makes an angle of 28.2 degrees with the horizontal. As the mass is pulled, the pulley rotates and the string is unwound. The radius of the pulley is 15.1 cm and it is twice as massive as the box. The pulley can be considered as a solid uniform disk. If the motion starts from rest, how many seconds later will the pulley have made 18 full turns? The image is attached of the pully. Thank you
You are riding your bicycle down the street at a speed of 16 m/s. Your bicycle's frame has a mass of 6.0 kg, and each of its two wheels has mass 2.2 kg and radius 0.34 m. Each wheel can be thought of as a hollow hoop (assuming that the rim has much larger mass than the spokes). What is the total kinetic energy of the bicycle (in Joules), taking into account both the translational and rotational motion?

A bicycle wheel with a radius of 350 mm and a mass of (2.40x10^0) kg is spinning freely on a work stand at a rate of 2.0 rev/sec when a (1.0000x10^0) kg kitten jumps on it radially, holds on and starts spinning around. What is the new rotational velocity of the wheel in units of rev/s? Treat the wheel as a thin hoop. Give your answer with three significant figures.
A fixed pulley has a moment of inertia of 0.689 kg m² and a radius of 0.165 m. A string, wrapped tightly around the pulley, has a block of mass 0.409 kg attached to its free end. With the string vertical and taut, the block is carefully released so it can descend under the influence of gravity. As the block falls, the string unwinds and causes the pulley to rotate, but does not slip on the pulley. What is the speed of the block in m/s after it has fallen through 0.66 m? Express your answer to 2 decimal places.
A 250-g mass hangs from a string that is wrapped around a pulley, as shown in the figure. The pulley is suspended in such a way that it can rotate freely. When the mass is released, it accelerates toward the floor as the string unwinds. Model the pulley as a uniform solid cylinder of mass 1.00 kg and radius 9.00 cm. Assume that the thread has negligible mass and does not slip or stretch as it unwinds. Determine the magnitude a of the pulley's angular acceleration. rad/s? a = Determine the magnitude of the acceleration a of the descending weight. a = m/s? Calculate the magnitude of the tension T' in the string. T =
