As the drawing illustrates, two disks with masses m1 and m2 are moving horizontally to the right at a speed of v0. They are on an airhockey table, which supports them with an essentially frictionless cushion of air. They move as a unit, with a compressed spring between them, which has a negligible mass. Then the spring is released and allowed to push the disks outward. Consider the situation where disk 1 comes to a momentary halt shortly after the spring is released. Assuming that m1 = 1.2 kg, m2 = 2.3 kg, and v0 = +4.1 m/s, find the velocity of disk 2 at that moment.

As shown in Figure P8.20, a bullet of mass m and speed v passes completely through a pendulum bob of mass M. The bullet emerges with a speed of v/2. The pendulum bob is suspended by a stiff rod (not a string) of length , and negligible mass. What is the minimum value of v such that the pendulum bob will barely swing through a complete vertical circle? Figure P8.20

A ring (2 kg, r = 1 m) rotates in a CW direction with initial angular velocity 10 s-1. A disk (4 kg, r = 1 m) rotates in a CCW direction with initial angular velocity 40 s-1. The ring and disk "collide" and eventually rotate together. Assume that positive angular momentum and angular velocity values correspond to rotation in the CCW direction.What is the initial angular momentum Li of the ring+disk system? kg m2 s-1 What is the final angular velocity ωf of the ring+disk system? s-1
A 3.0-kg mass is sliding on a horizontal frictionless surface with a speed of V=3.0 m/s when it collides with a 1.0-kg mass initially at rest as shown in the figure. The masses stick together and slide up a frictionless circular track of radius 0.40 m, as the drawing below shows. To what maximum height, h, above the horizontal surface will the masses slide. 7. 040 m
Disk A, with a mass of 2.0 kg and a radius of 40 cm, rotates clockwise about a frictionless vertical axle at 30 rev/s. Disk B, also 2.0 kg but with a radius of 20 cm, rotates counterclockwise about that same axle, but at a greater height than disk A, at 30 rev/s. Disk B slides down the axle until it lands on top of disk A, after which they rotate together. After the collision, what is their common angular speed (in rev/s) and in which direction do they rotate?
A uniform bar of mass M and length L is suspended on a frictionless hinge. A horizontally launched blob of clay of mass m strikes the bottom end of the bar and gets stuck to it. After that, the bar swings upward. What is the minimum speed v of the blob of clay before impact that would enable the rod to swing full circle?
A 2.40-kg cylindrical rod of length 2.00 m is suspended from a horizontal bar so it is free to swing about that end. A solid sphere of mass 0.25 kg is thrown horizontally with a speed v, = 13.5 m/s to hit the rod at the point A one-fifth of the way up from the bottom of the rod. The sphere bounces back horizontally with a speed v, = 9.50 m/s, while the rod swings to the right through an angle 0 before swinging back toward its original position. What is the angular speed of the rod immediately after the collision? rad/s (a) (b)
