Problem: A pulley, consists of a disk of radius R=0.2 m and mass M= 50 kg is mounted on a nearly frictionless axle. A string is wrapped lightly around the pulley, and you pull on the string with a constant force, F = 100 N. If the pulley starts from rest, what is the angular speed at a time At = 1 s later? Assume that the string does not slip on the pulley. Note: Moment of inertia of a...

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...
A wheel with radius 0.4m is mounted on an axle and is free to rotate. Beginning with the wheel at rest, a string wrapped around the edge of the wheel, is pulled with a force of 20 N . While the string is unwinding the wheel rotates through an angle of 10 rad . If the angular speed of the wheel after the string is pulled is 4 rad/s , what is the moment of inertia of the wheel?
A flywheel (a uniform solid cylinder of radius 0.25 m and mass 80 kg) is initially at rest, but free to rotate about the axis through its center. A belt wrapped around it is pulled off horizontally, providing a tangential force of 45 N to the outer rim of the flywheel for 2.00 s. Calculate the final kinetic energy of the wheel.
A string is wrapped around a pulley of mass m, radius r and unknown moment of interia. The pulley can rotate freely about its axis without friction. The loose end of the string is attached to a block of mass m. If the magnitude of the angular acceleration of the pulley is 7g/12r what is the moment of interia of the pulley?
