Suppose you have a 120 kg wooden crate resting on a wood floor, with coefficient of static friction
0.500 between these wood surfaces. (a) What maximum force can you exert horizontally on the crate
without moving it? (b) If you continue to exert this force once the crate starts to slip, what will its
acceleration then be? The coefficient of sliding friction is known to be 0.300 for this situation.
Suppose you are performing an experiment on a crate of 45-kg tools resting on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the crate just begins to move when your force exceeds 313 N. After that you must reduce your push to 208 N to keep it moving at a steady 25 cm/s. What is the coefficient of static friction between the crate and the floor?
