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
Question
Answer:
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
