Question

A 100-kg box is a rest on the floor. The coefficient of static friction between the box and the floor is 0.40, while the coefficient of kinetic friction is 0.20. You apply a rightward horizontal force of P = 300 N. Part B What is the normal force acting on the block?

Answer 1

Answer:

The normal force acting on the block is 980 N.

Explanation:

Mass of box = 100 kg

Coefficient of static friction = 0.40

Coefficient of kinetic friction = 0.20

We need to calculate the normal force

We know that,

When the object is placed on the flat surface then the normal force is equal to the weight of the object.

So. The normal force = mass x acceleration due to gravity

$N=mg$

Where, N = Normal force

m = mass of object

g = acceleration due to gravity

$N=100\times9.8$

$N=980\ N$

Hence, The normal force acting on the block is 980 N.
