the best advanced question of coordinate geometry of last 2 decades
In the mechanical system represented in the figure, the box, whose mass is "M", can move without fiction. At the initial moment the load of mass "m" (a ball) suspended on a thread deviates from the vertical to the angle θ and is released.
