A ball with mass m = 10kg is attached to one end of a massless string of length r = 5m.?
The other end of the string is fixed about a point. The ball rotates about this point at a frequency of 1 Hz/ While the ball is rotating, the string is reeled in until its length r = 3m. If the system is not otherwise disrupted in any way, what is the new frequency of rotation?
25/9 Hz
5/3 Hz
1 Hz
3/5 Hz
9/25 Hz
can you help out this hard and I've tried everything? Please
