1. suppose that the cart moves with a larger constant velocity. Will the frictional force be different from before? explain.
2. Does the magnitude of the frictional force seem to depend of the velocity of the cart? Explain
3. A block is sitting on a table, you pull on a string attached to the block, and the block doesn't move because the frictional force opposes you pull. you pull harder, and evnetually the block begins to slide along the table top. How does the frictional force just before the block begins started sliding compare to the frictional force when the block is actually sliding? explain.
4. What happens when a string is hung around a pulley? Is the tension force still transmitted fully from one end of the string to the other?
