A student pushes horizontally northward on a 1.5 KG textbook initially at rest. The book is located 1.0m from the edge of a long table. the coefficient of static friction is 0.25, and the coefficient of kinect friction is 0.20. The applied force is just enough to get the book to start moving and is maintained for 1.5 seconds after the motion has begun.
B) Determine the Applied force (Fa) of the student to get the book moving
Fnet = Fa + Ff
Fnet = mass* acceleration
|Fnormal| = |Fgravity| = |mass* g|
The Attempt at a Solution
I'm able to figure out that the normal force is 14.7 N, and that the force of friction is -3.675 N, (letting force against movement be negative). I'm just not sure how much force should be applied if it's "just enough to get the book to start moving"?
Any help would be greatly appreciated
