Answer 1

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 :

$f=\mu N\\\\=0.05\times 850\\\\=42.5\ N$

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