Question:
Compose a problem about the balls
Please do not post the problem here, post it the regular way and hire give a link.
The best one I will attempt to solve.
hanging ball mass M string length l attaches it to mass m on the table. coefficient of dynamic friction mu
let r be length of string not hanging thru hole.mass m is given initial velocity u.
derive the equation of motion (r,theta) of m.
(this was a Cambridge S level question circa 1958).
