Physics 204

I have a few questions.

1.The coefficient of sliding friction between steel skate blades and ice is .05. How much force must be applied to a 150lb. skater to maintain a constant velocity?

2. If it takes a force of 6 pounds to cause a 24 pound box to slide on a level surface, what is the value of the static friction?

3.If the coefficient of kinetic friction is 75% of the coefficient of static friction, how much force is needed to keep the box in problem 2 moving at a constant velocity?

  1. 1. The product of the two numbers is the required force.

    2. 6/24 = static friction coefficient

    3. 75% of previous answer x (24 lb)= ?
