object #1 slides along a surface (μk = 0.15) that makes a 20º angle with respect to the horizontal. Both objects are connected by a massless string that runs over a frictionless pulley (m = 10 kg, r = 0.25 m). Object #1 has a mass of 5 kg and object #2 has a mass of 20 kg. Apply Newton’s Second Law to each of the three objects to obtain a system of three equations and three unknows that can be solved to find the tensions and acceleration of this system. Then calculate the final speed of object #2 after dropping a distance of 2 m.

that if a support rope on the side of a tent is placed at a 45degree angle to the ground, it will provide maximum support for the tent.

a) How far away from the base of your 6-foot tent wall should you 8ft rope be placed in order to provide maximum support in a strong wind.
This is what I got:
sinC/8=sin45degre/6
sin angle C=70.5 so the 180 - (45+70.5)=64.5.
Sin64.5degree/a=sin45degree/6
The rope should be 7.66 feet away from the base of the tent.

What I don't know how to figure out is the second part:
b) As the tent size changes, so does the length of the wall, the length of the support rope, and the maximum support angle. Derive a general formula that will allow you to determine how far away from the base of the tent wall the end of the support rope should be. Now this is an oblique tent so there is no 90degree angle. Can anybody help figure this out?

Do they have to sleep on the surface so that they can breathe? They are mammals so surely they must sleep - they can't be like sharks who don't sleep as sharks are fish.
