Given that,
The weight of the object, W = 80 N
The coefficient of kinetic friction between an object and the surface is 0.4.
To find,
The force of friction.
Solution,
The force of friction is given by the formula as follows :
[tex]F=\mu_k mg\\\\=0.4\times 80\\\\=32\ N[/tex]
So, the required force of friction is 32 N.
An 80 N object experiences a friction force of 32 N when sliding through a surface with a coefficient of kinetic friction of 0.40.
Friction (F) is the force that resists the sliding or rolling of one solid object over another.
An 80 N object has a coefficient of kinetic friction with a surface of 0.40. We can calculate the friction force using the following expression.
F = μ × N = 0.40 × 80 N = 32 N
where,
An 80 N object experiences a friction force of 32 N when sliding through a surface with a coefficient of kinetic friction of 0.40.
