Question

What is the coefficient of friction of an object with a weight of 300 N and a force of friction of 150 N?

1
0.75
.5
0

Answer 1

0.5

Step-by-step explanation:

Given parameters:

Weight of object = 300N

Force of friction = 150N

Unknown:

Coefficient of friction = ?

Solution:

Frictional force is a force that resists the motion of a body.

It is mathematically expressed as;

frictional force = uN

Where u is the coefficient of friction

N = Normal force = weight of the object

Now input the parameters and find u;

150 = u x 300

u =
`(150)/(300)` = 0.5

The coefficient of friction here is 0.5
