Surfaces of copper and cast iron in contact have coefficient of static friction =1.05 and coefficient of kinetic friction e=0.29. Suppose a 0.15 kg smooth block of cast iron resting on top of a copper surface is being pulled with a force of0.50 N but does not move in response. What is the force of friction? %3D O 0.43 N O 1.50 N • 0.50 N O 3.50 N
