five books weigh 25 N
.2 *25 = 5N
There are six books in a stack, and each book weighs 5 N. The coefficient of static friction between the books is 0.2. With what horizontal force must one push to start sliding the top 5 books off the bottom one.
my answer is 3N but i don't think that's right.
does anyone know what the answer is ..?

Aren't there five books on top, so the normal force is 25N?
Friction=mu(normal force)
Friction=mu(normal force)
3 N
