Surfaces of copper and cast iron in contact have coefficient of static friction µs = 1.05 and coefficient of kinetic friction µk = 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 of 0.50 N but does not move in response. What is the force of friction?
0.50 N
3.50 N
1.50 N
0.43 N
I think its D

@Artkidl0l so would it be 0.50 or 0.43

izzyrawrz · Answer

Yea it is 0.50 I got it right @Artkidl0l Thank you.
