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 box of mass m = 10.0 kg is attached to a rope. The other end of the rope is wrapped around a pulley with a radius of 15.0 cm. When you release the box, it begins to fall and the rope around the pulley begins to unwind, causing the pulley to rotate. As the box falls, the rope does not slip as it unwinds from the pulley. If the box is traveling at a speed of 2.50 m/s after...

Q3-(25 pts) A pulley of mass Mand radius R can rotate around its center of mass freely. Take the moment of inertia of the pulley as 1o. A string with negligible mass is wrapped around the pulley. One end of the string holds a block with mass m and the other end is attached to a spring with a force constant k. Assume no friction at any surface and string is not slipping on pulley. a) When the system is...
