5. Because of a frictional force of 2.6 N, a force of 2.8 N must be applied to a textbook in
order to slide it along the surface of a wooden table. The book accelerates at a rate of
0.11 m/s?
a What is the unbalanced force on the book?
b. What is the mass of the book?

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
