The homework problem is confusing me a little bit especially b and c. I have attached the picture of the incline plane and object. Based on figure #1, assume the block is sliding down the inclined plane and that there is kinetic friction associated with the block and plane. Label all force vectors. B.Write a mathematical expression for all force vectors ensure that you use the proper sign. C.Using the mathematical expressions derived in step B derive an expression for the downward acceleration of the block.
