A rightward force of 36-N is applied to a book in order to move it across a table. The table where the book is placed provides a static friction with a maximum value of 20-N and Kinetic friction of roughly 12 N. If the book has a mass of 3.0-kg, what is the acceleration of the book?

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
