A rope is wrapped around the rim of a large uniform solid disk of mass 305 kg and radius 2.10 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest, what is its angular speed in rev/s at the end of 2.65 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 225 kg and radius 2.50 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest, what is its angular speed in rev/s at the end of 1.65 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 295 kg and radius 2.40 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest what is its angular speed in rev/s at the end of 1.95 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 315 kg and radius 1.60 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest what is its angular speed in rev/s at the end of 2.95 s?
A rope is wrapped around the rim of a large uniform solid disk of mass 315 kg and radius 2.40 m. The horizontal disk is made to rotate by pulling on the rope with a constant force of 195 N. If the disk starts from rest what is its angular speed in rev/s at the end of 1.75 s?
2-a rope is wrapped around a solid disk of radius R = 2.5 m and a mass of 1.5 kg . The disk rotates about its own axis. A bucket water has been tied to the other end of the rope as show in the figure. by the rotating disk. The mass of the bucket is 2.0 kg. SHOW FORMULAS AND COMPLETE SOLUTION UNDER EACH PART OF THE PROBLEM. a) calculate the moment of inertia/ Rotational inertia of the disk?...
The rope wrapped around the outer diameter of the disk is pulled at a constant speed of 1.75 m/s. If the outer radius is 2.26 cm and the inner radius is 0.28 cm, how fast does the hanging mass rise?
A light, flexible rope is wrapped several times around a hollow cylinder with a weight of 40.0 Nand a radius of 0.25 m, that rotates without friction about a fixed horizontal axis. The cylinder is attached to the axle by spokes of a negligible moment of inertia. The cylinder is initially at rest. The free end of the rope is pulled with a constant force P for a distance of 5.00 m, at which point the end of the rope...
A rope of negligible mass is wrapped around a 225-kg solid cylinder of radius 0.400 m. The cylinder is suspended several meters off the ground with its axis oriented horizontally, and turns on that axis without friction. (a) If a 75.0-kg man takes hold of the free end of the rope and falls under the force of gravity, what is his acceleration? m/s2 (b) What is the angular acceleration of the cylinder? rad/s2
A certain pulley is a uniform disk of mass 2.7 kg and radius 0.25 m. A rope applies a constant torque to the pulley, which is free to rotate without friction, resulting in an angular acceleration of 0.12 rad/s2. The pulley starts at rest at time t = 0 s. What is its rotational kinetic energy at t = 2.2 s?
