sweetwilliam said:Hi, thanks...i re-did the final rev/min and got 29.43 but when i put that back into my formula I am still not getting the answer that's in the book...thanks
sweetwilliam said:ok after using that number i got -.0064 rad/s^2 which is partially correct by why in the book does it say .0064, where did the neg. go?
Angular acceleration is the rate of change of angular velocity with respect to time. In other words, it measures how quickly an object's angular velocity is changing.
Angular acceleration is calculated by dividing the change in angular velocity by the change in time. The formula for angular acceleration is α = (ω2 - ω1) / (t2 - t1), where α is angular acceleration, ω is angular velocity, and t is time.
Angular acceleration is a measure of how quickly an object's angular velocity changes, while linear acceleration is a measure of how quickly an object's linear velocity changes. Angular acceleration is measured in radians per second squared, while linear acceleration is measured in meters per second squared.
The magnitude of angular acceleration is affected by the size and direction of the angular force applied to an object, as well as the object's moment of inertia. The moment of inertia is a measure of how difficult it is to change an object's rotational motion.
Angular acceleration is used in many real-world applications, from the rotation of objects in space to the motion of vehicles and machinery. It is especially important in areas such as robotics, aerospace engineering, and sports biomechanics.
