Ignoring the slippery when wet sign, a 150 kg man steps carelessly. What is the coefficient of friction if the force of friction was 25 N? Ignoring the slippery when wet sign, a 150 kg man steps carelessly. What is the coefficient of friction if the force of friction was 25 N?

5
A glacier has a mass of 5x10 10 kg and moves at a constant velocity of.5 m/day. If the force of friction between glacier and rock is.2, what is the force of friction scraping the rock below the glacier?

6
Slip tech is a product that treats surfaces to make them less slippery. If a 200 kg man stepped on each of these materials, how much more force of friction would he have with this product?
