When a chainsaw is in operation, the chain moves with a linear speed of v=5.9m/sv=5.9m/s. At the end of the saw, the chain follows a semicircular path with a radius of r=0.051mr=0.051m. Part A What is the angular speed of the chain as it goes around the end of the saw? Express your answer to two significant figures and include appropriate units. Part B What is the centripetal acceleration of the chain at the end of the saw? Express your answer to two significant figures and include appropriate units.
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.
