In Example 11.8, we investigated an elastic collision between a
disk and a stick lying on a frictionless surface. Suppose everything
is the same as in the example except that the collision is perfectly
inelastic so that the disk adheres to the stick at the endpoint at
which it strikes. Find (a) the speed of the center of mass of the
system and (b) the angular speed of the system after the collision.
A cylinder with a radius of 0.5 m and mass of 2.0 kg rolls down a frictionless ramp from a
height of 3.6 m. At the very bottom of the ramp, it collides with, and sticks to, a 5.0 kg mass
(i.e., it is a perfectly inelastic collision). This combined object now slides along the flat floor,
where the coefficient of kinetic friction is 0.56.
How far does the combined object travel along the floor before coming to a stop?
(Moment of inertia of cylinder is l=(1/2) mr2.)
A ring (2 kg, r = 1 m) rotates in a CW direction with initial angular velocity 20 s-1. A disk (4 kg, r = 1 m) rotates in a CCW direction with initial angular velocity 50 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
