PHYS121 - Learning Assignment: Static and Kinetic Friction 1. A 5kg object is sitting flat on a horizontal tabletop with a rough surface having friction coefficients us = .4 and us = .3. You push horizontally against one side with a pushing force of 10N. Will the object move? What is its acceleration? 2. You now double your pushing force against the object in question 1. Will the object move? What is its acceleration? 3. Now let's imagine the object from question 1 is actually on an inclined surface, angled at 30 degrees above horizontal. It is initially sitting still. What is the maximum pushing force you can apply against the side of the object aimed up the hill before it will begin to move? What is the maximum pushing force you can apply against the side of the object aimed down the hill before it will begin to move
