-. Solid disc with radius R=5 cm and mass M-4,5 kg is hanging on the ceiling. There is a rope wound around the disc. The rope is conducted through an ideal travelling pulley, and the end of the rope is fastened to the ceiling. The mentioned pulley carries a block with mass m=1kg. Find (a) the vertical translational acceleration of the block, (b) K=? force in the rope, (c) F=? force, which holds the disc on the ceiling. K ´R M m
In the figure, two 9.10 kg blocks are connected by a massless string over a pulley of radius 2.10 cm and rotational inertia 7.40 × 104 kg-m². The string does not slip on the pulley; it is not known whether there is friction between the table and the sliding block; the pulley's axis is frictionless. When this system is released from rest, the pulley turns through 0.900 rad in 170 ms and the acceleration of the blocks is constant. What are (a) the magnitude of the pulley's angular acceleration, (b) the magnitude of either block's acceleration, (c) string tension T₁, and (d) string tension T₂?

A sphere of mass M and radius R is not necessarily solid or hollow. It has moment of inertia I= cMR2. As shown in the figure, the sphere starts from rest and rolls without slipping down a ramp from height H. It then moves back up the other side, but now with no friction at all between the sphere and the ramp. What height does the sphere reach?
Rotational dynamics.
Net torque, moment of inertia, and constant angular acceleration The radius of the roll of paper shown below is 7.6 cm and its moment of inertia is I= 3.3 x 10-3 kg-m². The roll is initially at rest, then a downward force F = 3.5 N is exerted on the end of the roll for 1.3 s, as shown. A constant frictional torque (Tf.) with magnitude 0.11 N-m that slows the clockwise rotation acts on the roll from the moment it starts rotating until the moment it stops rotating. After the force F is removed (at the end of 1.3 s), the roll slows and eventually comes to a stop due to tr. Assume that the paper is so thin that the radius of the roll remains constant while it is unrolling. (a) Calculate the total length of paper that unrolls from the moment the force F was applied until the moment that the roll stops moving. (answer: 7.3 m) (b) The thickness of the paper is about 0.01 cm. Is the assumption that the radius of the roll remained constant justified? That is, estimate the fractional decrease in…
