Example F: A disk with a mass M, a radius R, and a rotational inertia of I= 2 MR2 is attached to a horizontal spring which has a spring constant of k as shown in the diagram. When the spring is stretched by a distance x and then released from rest, the disk rolls without slipping while the spring is attached to the frictionless axle within the center of the disk. Calculate the linear velocity of the disc. wwwwww

In our class model, wind is flowing along the X axis and torque is generated in the Y axis, with torque measurements in the other axes being near 0. What would happen in reality if the torque in the X axis were large, even larger than in the Y axis?

Joseph, Winston, and Franklin are doing an experiment in lab that involves rotational dynamics. Using the apparatus below, Joseph places a disk with a mass of 379 g on the apparatus. Winston then hangs a 15 g mass from the pulley and releases it. The 15 g mass drops and then rises back up, then drops again. They each graph the angular velocity ω as a function of time as the hanging weight drops, rises, and drops again. Their graphs are shown below. Only one is correct. Identify the correct graph and explain why it is correct. For the incorrect graphs, explain why they are not correct.

Here is a device that can rotate freely with little friction with the axle. The radius is 0.5 m, and each of the eight balls has a mass of 0.3 kg. The device is initially not rotating. A piece of clay falls and sticks to one of the balls as shown in the figure. The mass of the clay is 0.066 kg and its speed just before the collision is 8 m/s. * (a) Which of the following statements are true, for angular momentum relative to the the axle of the wheel? Just before the collision ₁ = 0.5/√√2 = 0.5 cos(45°) (for the clay). The angular momentum of the wheel is the same before and after the collision. The angular momentum of the wheel is the sum of the angular momenta of all eight balls. The angular momentum of the falling clay is zero because the clay is moving in a straight line. Just before the collision the angular momentum of the wheel is 0. The angular momentum of the wheel + clay after the collision is equal to the initial angular momentum of the clay. (b) Just after the collision,…
