HW 6.4. Consider two objects with mi > m2 connected by a light string that passes over a pulley of radius R and mass M. The string does not slip on the pulley or stretch. The pulley turns without friction about its axis of rotation as shown below. The two objects are released from rest separated by a vertical distance 2h. Treating the pulley as a uniform disk, (a) Use the principle of conservation of energy to find the translational...

Problem 5 Two objects, with mass ratio mi :m2 4 1, are sliding without friction on a horizontal surface. They are sliding towards the right, as shown in the figure. Both objects have the same speed v. The rightmost object is about to collide with a wall Then, a sequence of collisions involving the two objects and the wall will ensue. Your task is to figure out what is this sequence of collisions, and what are the velocities of both...

A small particle of mass m is at rest on a horizontal circular platform that is free to rotate about a vertical axis through its center. The particle is located at a radius r from the axis, as shown in the figure above. The platform begins to rotate with constant angular acceleration α . Because of friction between the particle and the platform, the particle remains at rest with respect to the platform. When the platform has reached angular speed...

Rotational motion
3) A horizontal circular platform can rotate around a vertical axis at its center with negligible friction. You decide to use the rotating platform to design a procedure that will allow you to determine the unknown rotational inertias of different objects, for example a bowl. You know the rotational inertia of the platform Ip. Which of the following procedures would serve your task? Comment on why. (More than one answer could be correct). Comment on the procedures that...

Two objects 1 and 2 of mass m_1 and m_2 are whirling around a shaft with a constant angular velocity omega. The first object is a distance d from the central axis, and the second object is a distance 2d from the axis. You may ignore the mass of the strings and neglect the effect of gravity. Draw a free body diagram and clearly identify your coordinate system and unit vector directions. What is the tension in the string between...
