A coffee cup of mass 230 g sits on a flat, horizontal table top. You push the cup across the table top with a constant speed of 3.2 cm/s. To do this, you must exert a horizontal force of magnitude 0.45 N.
What is the magnitude of the frictional force acting on the cup as you push it?

This time it's constant speed, so that means a=0, so \(\Sigma F=0\). Do you need further help?
