    Problem 1: You need to move a 125-kg piece of furniture in your living room. You and your friend exert a force of 305 N to start it moving. What is the coefficient of static friction between the furniture and the floor?

    Problem 2: A 20-kg bowling ball slides half way down a lane with a acceleration of 3.3 m/s^2before it starts to roll. What is the coefficient of kinetic friction between the ball and the lane that is starts rolling?
