# Rpm and Angular Acceleration

Not what you're looking for?

Question: The blades in a blender rotate at a rate of 7290 rpm. When the motor is turned off during operation, the blades slow to rest in 3.67 s. What is the angular acceleration as the blades slow down? The initial rotation is in the positive direction.

##### Solution Summary

This solution provides a detailed, step by step response which first conceptualizes how to approach understanding each of the variables used in angular acceleration problems. Secondly, this response constructs the equation which needs to be used to solve for the desired value and this is completed in a Word document.
