In the figure here, a cylinder having a mass of 1.5 kg can rotate about its central axis through point O. Forces are applied as shown: F₁ = 3.1 N, F2 = 9.3 N, F3 = 6.0 N, and F4 = 9.1 N. Also, r = 7.0 cm and R = 17 cm. Taking the clockwise direction to be negative, find the angular acceleration of the cylinder.

Answer the question in full details, thank you very much: The tub of a washer goes into its spin cycle, starting from rest and gaining angular speed steadily for 8.21 s,when it is turning at 4.99 revolutions/s. At this point the person doing the laundry opens the lid, and a safetyswitch turns off the washer. The tub smoothly slows to restin 11.6 s. Through how many revolutions does the tub turn while it is in motion?
A pulsar is a rapidly rotating neutron star. The Crab nebula pulsar in the constellation Taurus has a period of 33.5×10−333.5×10^-3 s, radius 10 km. And suppose its mass is 2.1×10302.1×10^30 kg. The pulsar's rotational period will increase over time due to the release of electromagnetic radiation, which doesn't change its radius but reduces its rotational energy. A. What is the angular momentum of the pulsar? Give your answer in the scientific notation, in the normalized form. L = x 10 js B. Suppose the angular velocity decreases at a rate of 4.7×10−144.7×10-14 rad/s2. What is the magnitude of the torque on the pulsar? Give your answer in the scientific notation, in the normalized form.
