Homework Statement
A 4kg object is palced on a table with a coefficient of friction of 0.2, and attached to a rope. This rope is run through a frictionless pulley, and attached to an 8kg weight. What is the tension in the rope?
Homework Equations
F=ma
F of friction = (coefficient of friction)(Force normal)
The Attempt at a Solution
Force normal of weight = 8(9.8) = 78.4
Force normal of object = 4(9.8) = 39.2
Force of friction on object = 0.2(39.2)
I don't know where to go from here, and I have an exam tomorrow. Help would be greatly appreciated, obviously :P
Thanks, I hear you guys are the best for quick physics help ;)
