Question

a lawn roller that is 30 inches in diameter makes one revolution every 5/6 second. find the angular speed of the roller in radians per second

Answer 1

5pi/3

Answer 2

how fast is the roller moving across the lawn?

Answer 3

sorry...its 12pi/5

Answer 4

and its moving at 12pi x 30 / 5 = 72pi in/sec

Answer 5

thank you so much!

Answer 6

try doing the urself....the linear velocity is the radius times the angular speed

Answer 7

And did you not use the diameter, him?

Answer 8

oh..right Mert....it sholud be 15 inches into 12pi/5

Answer 9

36 pi angular times radius

Answer 10

for which part?

Answer 11

Linear

Answer 12

Angular = 12 pi/5
Linear = 36 pi

Answer 13

thank you!
