What minimum coefficient of kinetic friction is required to bring the crate to a stop over a distance of 8.0m along the lower surface.
The kinetic friction coefficient between the lower block and the flat surface is 0.105. A horizontal force F = 95 N pushes against the upper block, causing it to slide. The friction force between th
