## Homework Statement

A child pulls a friend on a sled. The child maintains a constant tension of 29.4 N in the rope. The combined mass of the friend and sled is 30.0 kg, and the coefficient of sliding friction between the sled and snow is 0.1. How far can the child pull her friend in 6 sec?

## Homework Equations

F = ma

fk = muk x FN

Ff = mu x FN

Fw/2 = FT

## The Attempt at a Solution

so I got the force weight of the child and the sled is 294 N

so the force normal of the child and sled is 294N

fk = 0.1 x 294 = 29.4

and the force tension is 29.4 so 29.4 = Fw/2

= 58.8 N = Fw but i don't know what weight that is

and i need another equation to put this in but i don't know which one
