A block weighing 32.7 N is sitting on a table. Your friend pushes down on the block with a force of 26.6 N. The static coefficient of friction between the block and the table is 0.24. The kinetic coefficient of friction is 0.20. You pull horizontally to the right with a force F on a string that is attached to the right side of the block.

What is the minimum force you need to exert to get the block to start moving?

What the force required to keep the block moving at constant speed?
