A ceiling fan has 17 -inch blades (so the radius of the circular fan is 17 inches). Suppose the linear speed of the tip of a blade is 9 feet per second. (a) Find the angular speed of the fan in radians per minute. (b) Find the number of revolutions a blade makes per minute. Do not round any intermediate computations, and round your answer to the nearest whole number.
Angular displacement: When a rigid body rotates about a fixed axis, the angular displacements is the angle swept out by a line passing through any point on the body and intersecting the axis of rotation perpendicularly. By convention, the angular displacement is positive if it is counterclockwise and negative if it is clockwise. SI Unit of Angular Displacement: radian (rad)Angular displacement is expressed in one of three units:Degree (1 full turn 3600 degree) Revolution (rev) RPM Radian (rad) SI unit
i dont understand...
im not done explaining
jus w8
oh sorry
here how aboout this ima make u an power point itll taske about 10 min so ya just a bit:D
it should help u alot
thank you! i feel like i have answer possibilities but I'm not sure they are correct...
I made this a while ago for my class i hope itl help you aswell
As you can ssee i dont realy give a pellet about my spelling xD
its okay, i know how to do angular speed i just don't understand this particular example
ahh i seee
i still don't get it...
well give me your answer geusses
either 3 or 17 for a and 249 for b
whats 9 times 17?
153
correct
D you see where im going here?
not really...

i know you have to do that to get b
so what do u think you must do to get a?^_^
convert it to minutes and ft
kepp going
and multiply by 60
and then
i get 540ft/17in or 45 in/17in i converted it to inches
if i converted it to ft i got a big number that didn't look right
well i cant give u the answer
so ima leave you here i think you can get it
i know, I'm just trying to figure out what I'm doing wrong
well i gtg so try you best i sure u can get it right
i don't think i can buy thanks!t
