2. You are initially pushing a book across a level table at a constant velocity under the influence of kinetic friction. You are pushing the book parallel to the table. At t = 0 s, you reduce the magnitude of your force at a constant rate to o N over the course of 10 s. For the first 5 s of this time the book is still sliding, however during the last 5 s the block is at rest with respect to the table. Use a coordinate system such that the points in the direction of the initial velocity vector.
e. Write down an equation that describes the acceleration as a function of time. f. Sketch a graph of the x component of the velocity of the book. g. Write down an equation that describes the velocity as a function of time. h. Sketch a graph of the x component of the position of the book. i. Write down an equation that describes the position as a function of time.
