The coefficient of static friction between a block and a horizontal floor is 0.35, while the coefficient of kinetic friction is 0.22. The mass of the block is 4.6 kg and it is initially at rest.
(a) What is the minimum horizontal applied force required to make the block start to slide?
(b) Once the block is sliding, if you keep pushing on it with the same minimum starting force as in part (a), does the block move with constant velocity or does it accelerate?
(c) If it moves with constant velocity, what is its velocity? If it accelerates, what is its acceleration?
