High Physics

Recently I went up with physics and stuck up in few problems. Please if you can sought me out of this.

Prob.1 : A triangle base 12m long, height 8m .Find the largest area of rectangle that can be made inside the triangle, given one side of rectangle is along the base of triangle.(well use differentiation)

Prob.2 : Three identical sphere kept on smooth horizontal surface and they are in contact . A fourth identical sphere is kept symmetrical on these 3 spheres. find initially (a) acceleration of each sphere (b) normal force between 4th and 1st sphere.

Prob.3 : solve above question if 4 on horizontal surface , 5th symmetrically above the four.

Prob.4 : Consider a system with a pulley attached to surface. this pulley has a Block A on one side of string and other pulley on the other side of string, now this 2nd pulley has again a block on one side of string and other pulley on other side of string, now this 3rd pulley similarly has a bock on one side of string and another pulley on other side of string and so on up to infinity. Find acc. of Bock A if all blocks have mass m

These are the few ques I got problem, to be fair i don't know answer of any one :P and that's why i hope brillianties would help me out. I will be further publishing more questions. Please contribute to the note.
