A wheel with a radius 10 inches covers a distance of 40pie inches in one second. What is the angular speed of this wheel? A) 2pie radians per/secB) 4pie radians per/secC) pie radians per/secD) 2 radians per/secE) 4 radians per/secF) None of these
Accepted Solution
A:
angular velocity is given by: Ο=v/r where: Ο=angular velocity v=linear velocity r=radius From the question; v=40Ο inches/sec r=10 therefore: Ο=40Ο/10= 4Ο radians per per/sec
