# Save all ants from Monster Cube !

Classical Mechanics Level 5

Table

A solid Cube of side Length L and Mass M is moving on horizontal smooth table with velocity $${ V }_{ o }$$ . ( Side View is shown in figure )

An ridge ( Considered it as a Small stone ) is fixed at the corner of table.( Red coloured,as shown )

And If below the table , there are infinitely many ants are eating their food !

Then Find The Maximum velocity of Cube so that No ant get Hurt !

If Maximum Velocity can be expressed as :

$${ V }_{ o,max }\quad =\quad \sqrt { \cfrac { a(\sqrt { b } -c) }{ d } gL }$$.

Then Find value of : " a + b + c + d " ? ?

Details And Assumptions

$$\bullet$$ gcd(a,d) = 1 & gcd(a,c) = 1 & gcd (c,d)=1 & 'b' is square free integer.

$$\bullet$$ Ant's are infinite in numbers and present at everywhere on the ground .

$$\bullet$$ Assume If Cube Falls then ant's get Hurt .
