Answer:

b. 5 N

Explanation:

Each book weighs 5 N. Therefore, five books weigh 25 N. The friction force is:

Ff = Fn μ

Ff = (25 N) (0.2)

Ff = 5 N

The horizontal force one must push to slide the top five books off the

bottom one is 5 N

We were told that the 6 books each weigh 5N and we need to slide 5 of

them which is 5×5= 25N

We can then calculate the friction force with the formula below.

F = N μ

where F is frictional force, N is force and μ is coefficient of static friction

F= (25 N) (0.2)

F= 5 N
