Question

A helicopter blade spins at exactly 180 revolutions per minute. Its tip is 10.00 m from the center of rotation. What is its average velocity over one revolution

Answer 1

5.8E-3m/s

Step-by-step explanation:

Using

V= d/t

V= velocity

d= distance

t= time

But d= 2πr

But 180rev= 1min

So 1min/180= 60s/180

So

Vavr= 2π(10m)/180*60

=5.8E-3m/s
