## Homework Statement

You place a book flat on a table and press down on it with your right hand. The hand-to-book and table-to-book coefficients of kinetic friction are 0.47 and 0.44 respectively. The book's mass is 0.84 kg and your downward push on it is 9.00 N. Now, you use your left hand to push the book along the table at constant speed. Assuming that your right hand is stationary with respect to the table, what is the horizontal force exerted on the book by your left hand?

## The Attempt at a Solution

think its got something to do with the fact that the two friction coefficients are like a sandwich on the book. the x direction equation is the force you push the book with minus the two frictions added together= mass times acceleration but I can't get it to work. HELPPPPPPPPPPPPPPP I've spent an hour on this any push in the right direction is appreciated before I lose my damn mind
