hey..i have a problem that states. a record has an angular speed of 34.6 rev/min. Find its Angular speed in rad/s.(adsbygoogle = window.adsbygoogle || []).push({});

-so the answer is 3.623.

The second part of the problem asks what angle, in radians, does it rotate in .717s. answers in rad.

do you think you can help me?

Also, i have some problems dealing with a ball at the end of the string with length 1.8m. It is in horizontal circle at constant speed. IT makes 3.4 rev/s. I need to find the period of the ball's motion, the frequency, and its angular velocity...but everything i have tryed has failed.

I tryed 1.848 and .18726 for the period but was wrong. i tryed 5.34 and .5411 for the frequency but was wrong and the velocity i also got wrong.

PLEASE HELP! im new
