vo R R before after Consider m, Ip,R, vo and b to be given. Express your answers as formulas in terms of these gívens. a. Determine the angular momentum Lị of the blob-drum system just before the collision. b. Determine the angular momentum Lf of the blob-drum system just after the collision. c. Determine the moment of inertia Ig of the blob about the drum's center, after it sticks.
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
)A small blob of putty of mass ?? moves horizontally at speed ??0 along the path shown at left. A large, solid, uniform cylindrical drum, of moment of inertia ?? and radius ?, is initially at rest but can rotate without friction about a fixed axis through its center. The putty blob strikes the drum and sticks to it, and they rotate together as shown at right.
