Homework Equations
The Attempt at a Solution
Consider the system at time t (see attachment, I am representing the blocks as point masses)
The component of acceleration along the string is ##a_0\cos \theta##. This is the acceleration of the other two blocks at the sides. The component of acceleration along the horizontal direction is ##a_0 \sin \theta \cos \theta##.
[tex]v\frac{dv}{dx}=a_0 \sin \theta \cos \theta[/tex]
As ##x=l\sin \theta##, ##dx=l\cos \theta d\theta##
[tex]vdv=a_0 \sin \theta \cos^2 \theta d\theta[/tex]
The problem is, what should be the limits for ##\theta##? And is my working even correct?
Any help is appreciated. Thanks!
