A freely spinning wheel of mass M and radius R and moment of inertia I has its center attached to a fixed point a distance H above the ground. A thin thread is wrapped around the edge of the wheel, and connected to a mass, M (same as the wheel). When the mass is released from rest, it falls the distance H in a time delta t. In terms of M, g, I and H, how much time, delta t,...

A bicycle wheel of mass M and radius R is placed on a vertical axle and is able to rotate without friction. A dart of mass, m is fired toward the wheel with an initial velocity v(o). The dart strikes the wheel and sticks in the tire. The moment of inertia of the wheel is I=mr^2. What is the initial angular momentum of the dart with respect to the center of the wheel? What is the angular velocity of the...

In the figure, a very light rope is wrapped around a wheel o radius R = 2.0 m and does not slip. The wheel is mounted with frictionless bearings on an axle through Its center. A block of mass 14 kg is suspended from the end of the rope. When the system is released from rest it is observed that the block descends 10 m in 2.0 s. What is the moment of Inertia of the wheel?
A uniform wheel of mass 10.0 kg and radius 0.400 m is mounted rigidly on an axle through its center
A uniform wheel of mass 10.0 kg and radius 0.400 m is mounted rigidly on an axle through its center (see figure . The radius of the axle is 0.200 m, and the rotational inertia of the wheel-axle combination about its central axis is 0.600 kg·m2. The wheel is initially at rest at the top of a surface that is inclined at angleθ = 43.6o with the horizontal; the axle rests on the surface while the wheel extends into a...

A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass.
A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass. The axis is perpendicular to the disk. The moment of inertial for the disk with a central axis is I MR2. Two non-rotating smaller disks, each with mass M2 and radius R/4, are glued on the original disk as shown in the figure. (a) Show that the ratio of the moments of inertia is given by I'/I = 35/16, where I' is the moment...

Questions 1-2 A ball of mass m and radius r (moment of inertia lmm) is placed on the inside of1 a frictionless circular track of radius Ro as shown in the igure. It starts from rest at the vertical edge of the track, and since there is no friction, it slides down without rotation. 1. What will be the speed of its center of mass when it reaches the lowest point B of the track?
