The coefficient of kinetic friction between an object and the surface upon which it is sliding is 0.40. The weight of the object is 80N. What is the force of friction?

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.

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 :

So, the required force of friction is 32 N.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
