a forward horizontal force of 3 lb is used to pull a 60 lb sled at constant velocity on a frozen pond. the coefficent of (kinetic) friction is:

1. 0.2
2. 0.05
3. 0.5
4. 20
5. 2

It’s either 0.05 or 20. Assuming that the coefficient friction is a damping factor, I feel like 0.05 would be correct m

The coefficient of kinetic friction is 0.05

The correct answer to the question is Option (2) 0.05

From the question given above, the following data were obtained:

Force (F) = 3 lb

weight (W) = 60 lb

Coefficient of friction (μ) = ?

The coefficient of friction can be obtained as follow:

[tex] \mu \: = \frac{force}{weight} \\ \\ \mu \: = \frac{3}{20} \\ \\ [/tex]

μ = 0.05

Therefore, the coefficient of friction is 0.05
