Question 1169873
.


As I read the problem, my understanding is that the ball is attached to a string and to a line, at the same time.


                                It  PERPLEXES  me.

Wording is very poor.


When professional people formulate problems in Math or Physics, they usually strive to make it as clear as possible, 

thinking about a reader.



When, in opposite, people create/compose the problems as you do in your post, they are   U N P R O F E S S I O N A L,

and their posts are good for re-cycling, ONLY.

I love to help students and I love to solve Physics problem.


But when the problem comes written so carelessly,  I really don't know what to do . . .
