PLEASE HELP SIMPLE QUESTION 90 POINTS 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!
