Homework Statement
A ball, 1.8 kg, is attached to the end of a rope and spun in a horizontal circle above a student's head. As the student rotates the ball in a horizontal clockwise circle their lab partner counts 53 rotations in one minute. What is the ball's angular velocity in radians per second?
Relevant Equations
multiply 5.55 by 2pi to get angular velocity of 34.8717

What should I have done to more accurately solve the problem with a better understanding?

What other steps should I take when solving similar problems?

and lastly,
Is the mass relevant to the problem in any way?

Right. Why continue past that? You are asked for it in units of rad/sec.

So this is only a conversion problem?
Thanks you very much.

When I turned in that answer, it was still wrong.
