# It’s a snowy day and you’re pulling a friend along a level road on a sled. You’ve both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. You’ve been walking at a steady m/s, and the rope pulls up on the sled at a angle. You estimate that the mass of the sled, with your friend on it, is kg and that you’re pulling with a force of N. What answer will you give?

The co-efficient of friction is

See the step by step solution

## Step 1. Given Information

We have,

the rope pulls up on the sled at a angle

and with your friend on it, is kg and that you're pulling a force of N

## Step 2. Find the friction

the free body diagram, as shown above, with the pulling tension force of the rope acting at a angle with the horizontal on the sled, the friction , weigh and normal reaction

we can express the coefficient of friction as
