Part B Find the linear acceleration of its center of mass. Express your answer in meters per second squared. Part D If the disk is replaced by a hollow, thin-walled cylinder of the same mass and diameter, what will be the linear acceleration of its center of mass? Express your answer in meters per second squared.
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 thin, light string is wrapped around the rim of a 3.75-kgkg, solid, uniform disk (similar to a puck on ice without friction) that is 33.0 cmcm in diameter. A person pulls on the string with a constant force of 98.00 NN tangent to the disk, as shown in the figure below (Figure 1). The disk is not attached to anything and is free to move and turn.
