In the system shown below, there is a block of mass M = 3.6 kg resting on a horizontal ledge. The coefficient of kinetic friction between the ledge and the block is 0.25. The block is attached to a string that passes over a pulley, and the other end of the string is attached to a hanging block of mass m = 2.2 kg. The pulley is a uniform disk of radius 7.9 cm and mass 0.66 kg. Find the...

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...

2. A uniform, solid cylinder with mass M and radius 2R is on an incline plane with angle of inclination of 6. A string is attached by a yoke to a frictionless axle through the center of the cylinder so that the cylinder can rotate about the axle. The string runs over a disk-shaped pulley with mass M and radius R that is mounted on a frictionless axle through its center. A block of mass M is suspended from the...

A 3 kg block (block A) is released from rest at the top of a 20 m long frictionless ramp that is 4 m high. At the same time, an identical block (block B) is released next to the ramp so that it drops straight down the same 4 m. Find the values for each of the following for the blocks just before they reach ground level. (a) gravitational potential energy Block A ? Block B ? (B) kinetic...

(1) A thin stick is glued to a uniform disk to form a composite pulley. Then a non-slip string with two masses is hung over the disk and the system is released from rest. Uniform Disk mass: 4 kg radius: 5 cm Calculate the moment of inertia of the stick plus disk combination and find the angular acceleration of the composite pulley, the linear acceleration of the two hanging blocks, and the tensions in each part of the string (which...

A 65-N weight is released from rest and falls to the floor as shown in the figure. It is suspended by a string of negligible mass that is wrapped around a 5.0 kg pulley that is essentially a solid disk of a radius of 1.75 m and rotates through 5.5 radians. What is the angular speed of the pulley? (Note: Since the pulley has mass, the sum total of the forces acting on the pulley is not simply the weight...

Question 3. Two blocks having mass m (2 kg) and m, (5 kg) are connected by a string passing over a pulley as shown in the figure. The pulley (in cylindrical disc shape) has a radius R (0.4 m) and mass (0.5 kg). The string does not slip on the pulley and the system is released from rest. Find the translational speeds of the blocks after mass 2 descends through a distance h (1.0 m) and find the angular speed...

4. A 6-kg block (my), initially at rest on a rough shelf, is connected to a 4-kg block (m2) that hangs by an inextensible string of negligible mass passing over a pulley. The uniform disk-shaped pulley, having a mass of 3.0-kg and a radius of 10 cm, rotates about the symmetry axis through its center. The 6-kg block, which is attached to the spring, is initially pushed against the spring compressing it a distance of 30 cm from its equilibrium...

The figure shows a 100-kg block
being released from rest from a height of 1.0 m. It then takes it
0.90 s to reach the floor. What is the mass m of the other
block? The pulley has no appreciable mass or friction.

1. A 4 kg block is placed on a smooth 30° incline and released from rest, but a string connected to the block runs up the incline parallel to the surface, over a frictionless pulley, and horizontally to a 6 kg block on a level surface with a kinetic friction coefficient of 1/6. Find the acceleration of the system and the speed at the end of 4 s assuming the 6 kg block doesn't run into the pulley first. 2....
