Estimate the value of the coefficient of kinetic friction ?k for a medium‑sized cardboard box full of books on typical office carpet.

Solutions

Expert Solution

The more the weight the more will be kinetic friction. We can approximately say using the properties of carpet that the coeficient of kinetic friction is approximatel from 0.5 to 0.98
