d , e and f f. Sketch a graph of the x scalar component of the friction force as a function of time. Remember, for thefirst 5 seconds it will be a kinetic friction, but for the last 5 seconds it will be a static friction.g. Sketch a graph of the x scalar component of the acceleration of the book as a function of time.h. Write down an equation that describes the velocity vector as a function of time, for 0-5s. You can callthe velocity of the book at t = 0 v.i. Write down an equation that describes the position vector as a function of time, for 0-5s. You can callthe position of the book at t = 07. 3. You are pushing a book with a force Fy, to the right across a level table at a constant velocity under theinfluence of kinetic friction. At t = 0 s, you reduce the magnitude of your force from F, to 0, at a constantrate over the course of 10 s. For the first 5 s of this time the book is still sliding, however during the last 5 sthe book is at rest with respect to the table. Use a coordinate system such that the î points to the right.a. Write an expression to describe the scalar component of your pushing force in the x-direction as afunction of time. Remember, it has a value of F, at t = 0 and linearly decreases until it reaches 0 att = 10s. (This step has nothing to do with forces or physics, it is purely mathematical.)b. In which direction does the acceleration of the book point? In which direction does the parallelcomponent of the contact force (a.k.a. the friction force) point?c. Draw a FBD for the book.d. Write a Newton's 2nd Law equation for the book. Leave å as a variable, since we know it is differentfrom 0-5s than from 5-10s.e. Describe in, words or equations, the magnitude of the friction force from 0-5s (when it is kineticfriction). What is the kinetic friction force in terms of F,? (Hint: think about the motion of the bookbefore t = 0.) Describe, in words or equations, the magnitude of the friction force from 5-10s (when itis static friction).
