95 POINTS PLEASE HELP SIMPLE QUESTION

A student and the waxed skis she is wearing


have a combined weight of 850 newtons.


The skier travels down a snow-covered hill


and then glides to the east across a snow-covered, horizontal surface.



2. Determine the magnitude of the normal force exerted


by the snow on the skis as the skier glides across the


horizontal surface.


3. Calculate the magnitude of the force of friction acting on the skis as the skier glides across the snowcovered, horizontal surface. [Show all work, including


the equation and substitution with units.]



I already know 2 is 850. But how do you get the coefficient of friction for 3. brainliest to best answer!

Respuesta :

Given that,

Combined weight of a student and the waxed skis, W = 850 N

It should be given that the coefficient of friction is 0.05.

To find,

The magnitude of the normal force exerted and the magnitude of the force of friction.

Solution,

Normal force = weight of the object,

Here, weight = 850 N

Normal force = 850 N

Let f is the force of friction. It can be calculated as follows :

[tex]f=\mu N\\\\=0.05\times 850\\\\=42.5\ N[/tex]

Hence, the normal force is 850 N and the magnitude of the force of friction is 850 N.
