circular path,radius4cm,frequency4Hz,how longwill it take to move a distance circular of 16pie cm along circle

Answer 1

I'm not sure. It could be half a second. I dont know

Answer 2

Circumference 2 pie R.

Frequency 4 Hz means 4 times round the circle in one second.

Distance travelled in one second is 4 x 2 pie R = 8 pie R.

For travelling 8 pie R it takes one second.

For travelling 16 pie R it will take (16 pie R) / (8 pie R) = 2 second.

Answer 3

Frequency of what?

You need either linear velocity or angular velocity. This is just my guess as to the direction of this problem... You didn't give enough details.

Once you have a velocity, you can divide distande by velocity to obtain time.
