4. Re-do problem 2 above, except now the pulley has mass, M=0.75 kg, and is a uniform disk (1 = y; MRP) with radius R = 7.50 cm. The pulley would not slip against the string. All other quantities are the same. Again: (a) The system is initially stationary. With a calculation, determine whether the blocks stay stationary (b) If the blocks stay stationary, find the tension in the string: OR If the blocks start moving, find the acceleration of...

The system shown in the figure below consists of a mass M = 3.3-kg block resting on a frictionless horizontal ledge. This block is attached to a string that passes over a pulley, and the other end of the string is attached to a hanging m = 1.7-kg block. The pulley is a uniform disk of radius 8.0 cm and mass 0.60 kg. (a) What is the acceleration of each block? acceleration of M = 3.3 kg _____ m/s2 acceleration...

A small 0.270-kg object moves on a frictionless horizontal table in a circular path of radius 1.70 m. The angular speed is 9.60 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 102 N, what is the...

A small 0.501-kg object moves on a frictionless horizontal table in a circular path of radius 1.16 m. The angular speed is 5.51 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 112 N, what is the...
A string is wrapped around a uniform disk of mass M = 2.2 kg and radius R = 0.1 m. (Recall that the moment of inertia of a uniform disk is (1/2) MR2.)
A string is wrapped around a uniform disk of mass M = 2.2 kg and radius R = 0.1 m. (Recall that the moment of inertia of a uniform disk is (1/2) MR2.) Attached to the disk are four low-mass rods of radius b = 0.13 m, each with a small mass m = 0.7 kg at the end. The device is initially at rest on a nearly frictionless surface. Then you pull the string with a constant force F...
