Question

A model helicopter has a rotor blade length of 3.0 m from the motor to the tip, and the blades rotate at a speed of 544 rpm.

rpm means revolutions per minute, where 1 revolution is when the blades rotate around one full circle.

What is the speed of the tip of the blade in m/s?

Answer #1

A helicopter blade spins at exactly 105 revolutions per minute.
Its tip is 7.00 m from the center of rotation.
(a)
Calculate the average speed (in m/s) of the blade tip in the
helicopter's frame of reference.
m/s
(b)
What is its average velocity (in m/s) over one revolution?
m/s

---- A centrifuge is a common laboratory instrument that
separates components of differing densities in solution. This is
accomplished by spinning a sample around in a circle with a large
angular speed. Suppose that after a centrifuge in a medical
laboratory is turned off, it continues to rotate with a constant
angular deceleration for 10.7 s before coming to rest.
A) If its initial angular speed was 3830 rpm , what is the
magnitude of its angular deceleration?
B) How...

Energy Trevor Baylis was quite a swimmer in his youth, representing
Britain at the age of 15. So it wasn’t entirely surprising that he
ended up working for a swimming pool firm in Surrey before setting
up his own company. He continued his swimming passion – working as
a part-time TV stuntman doing underwater feats – but also followed
an interest in inventing things. One of the projects he began...
