Question

Please help, will medal and follow :)
Determinate angular velocity if 29 revolutions are completed in 2 seconds.
___ radians/s

Answer 1

do u know the formula for angular velocity?

Answer 2

sorry, no :|

Answer 3

can you please walk me through it?

Answer 4

\[\omega=2(pi)f\]

Answer 5

f-frequency

Answer 6

which one is the frequency?

Answer 7

frequency=1/time period,time period = total no. of. revolutions/ total time taken

Answer 8

29/2?

Answer 9

2(pi)*14.5?

Answer 10

1/14.5 since 14.5 is the time period... we want frequency..

Answer 11

2pi/14.5

Answer 12

1 revolution is 2 pi radians

29 revolutions is 29 * 2 pi radians

29 revolutions in 2 seconds is 29 * 2 pi radians / 2 seconds = 29 pi radians/second
