The combination of an applied force and a frictional force produces a constant torque of 40 N·m on a wheel rotating about a fixed axis. The applied force acts for 8.0 seconds, during which time the angular speed of the wheel increases from 0 to 700 degrees/second. The applied force is then removed, and the wheel comes to rest in 55 s. Answer the following questions. (a)What is the magnitude of the angular acceleration of the wheel while the applied...

A pulley, with a rotational inertia of 1.7 ✕ 10−3 kg · m2 about its axle and a radius of 11 cm, is acted on by a force applied tangentially at its rim. The force magnitude varies in time as F = 0.50t + 0.30t2, where F is in newtons and t in seconds. The pulley is initially at rest. At t = 4.0 s what is its angular velocity (in rad/s)?

A potter’s wheel, a thick stone disk of radius 0.500 m and mass 100 kg, is freely rotating at 70.0 rev/min. The potter can stop the wheel by pressing a wet rag against the rim and exerting a radially inward force of 35.0 N. If the applied force slows the wheel down with an angular acceleration of 0.875rad/s2 , calculate the torque acting on the wheel and the coefficient of kinetic friction between the wheel and the rag
