A yo-yo is made by wrapping a string several times around a solid cylinder with mass M=9kg and Radius=5cm. You hold the end of the string stationary while releasing the cylinder. The string unwinds but does not slip or stretch as the cylinder drops and rotates. 1) Use energy to find the speed in vcm (cm/s) of the centre of mass of the solid cylinder after it has dropped a distance h equal to h=23cm 2) Find the acceleration of the centre of mass of the yo-yo. (m/s) 3) Find the tension on the string (N)

A light, nonstretching cable is wrapped around a solid cylinder with mass 88 kg and radius 0.19 m. The cylinder rotates with negligible friction about a stationary horizontal axis. We attach the free end of the cable to a block of mass 48 kg, and release the block from rest at a distance 3.9 m above the floor. As the block falls, the cable unwinds without stretching or slipping. Find the angular speed of the cylinder (in radians/s) the moment...

A weight with mass mw=150 gmw=150 g is tied to a piece of thread wrapped around a spool, which is suspended in such a way that it can rotate freely. When the weight is released, it accelerates toward the floor as the thread unwinds. Assume that the spool can be treated as a uniform solid cylinder of radius R=4.00 cmR=4.00 cm and mass Ms=100 gMs=100 g . Find the magnitude aa of the acceleration of the weight as it descends....

We wrap a light, flexible cable around a solid cylinder with mass 0.95 kg and radius 0.23 m . The cylinder rotates with negligible friction about a stationary horizontal axis. We tie the free end of the cable to a block of mass 1.84 kg and release the object with no initial velocity at a distance 1.58 m above the floor. As the block falls, the cable unwinds without stretching or slipping, turning the cylinder. Suppose the falling mass is...

A solid cylinder has a mass of 100 kg and radius 0.225m. The cylinder is attached to a frictionless horizontal axle. A long (light weight) cable is wrapped around the cylinder. Attached to the end of the cable is a 1.50 kg mass. The system is initially stationary. The hanging mass is then released. The mass pulls on the cable as it falls and this causes the cylinder to rotate. a) What is the velocity of the hanging mass after...

A small, solid cylinder with mass = 20 kg and radius = 0.10 m starts from rest and rotates without friction about a fixed axis through its center of mass. A string is wrapped around the circumference of the cylinder and pulled using a constant force F. The resulting angular acceleration of the cylinder is 5.0 rad/s2. What's the angular velocity after 4.0 s, in radians per second? (The moment of inertia of the cylinder is 1 half M R...

You throw a yo-yo of mass 30.0 g straight down with a linear speed of 1.00 m/s and an angular speed of 2.00 rotations per second. Once the yo-yo has dropped 1.00 m, it stops and rotates in place. Treat the yo-yo as a hollow cylinder with a radius of 3.00 cm. Assume energy is conserved. Find angular speed (in radians/second) of the yo-yo after it has fallen 1.00 m. Does this speed seem realistic? If not, what might explain...
