# Homework Help: What is the magnitude of force of friction of the snow

1. Oct 15, 2007

seld pulled at a constant velocity acroos a horizontal snow surface, if force 80 apploed to the sled rope at an angle of 53 to the ground,
what is the magnitude of force of friction of the snow???
i don't know how to solve it
i have test 2morrow
i need some explanition plez

And get used to the other rules: we are not here to answer your homework questions for you. You must show some of your effort before we help you.

Do you have a textbook? Read a bit about components of vectors, and coefficient of friction, and normal force.

i read the whole chapter and i still don't get it
i know the compnents of vector
first step i think
to get normal force::
80(cos53)
and you get
48 N
and i'm stuck!!
i know that i have to find the coffecient of the friction
so i can get Ff
that's not a homework, i'm studying for a test
thanks

This is not on a slope. You don't need the normal force here, actually. You need to know a few other things.

What's the net force on this object if it is pulled at a constant velocity?
