Questions?

Physics in Staten Island, NY

Hi, I am taking a college physics course and wanted know if you could help me with the following problems? Also, how much would you charge to help me answer these questions and understand how to solve them? Thank you, Jason 1. Find mass density of a 5.5 kg stone, which, when attached to a block of wood with dimensions 10x10x50 cm^3 will sink in water. Mass density of wood is 0.3 cm^3. 2. Two light weight buckets of volumes 8 and 10 liters full of water are connected by a light cord passing over a solid steel pulley of a diameter of 80 cm and a thickness of 5 cm. Find the acceleration (direction and magnitude) of the buckets. Mass density of steel is 8 g/cm^3. 3. In a room, a wooden ladder leans against a wall making an angle of 60 degrees with respect to the horizontal. The floor and the walls in the room are made of stone tiles. Find coefficient of friction between stone and wood.
