Question #216110

In the figure below, m1 = 6 kg, and m2 = 4 kg,. When the system is moving, the tension in the string is observed to be 30 N. What is the coefficient of kinetic friction between m1 and the table top?

Expert's answer

"\\mu m_1 g=(m_1-m_2)g-T\\\\\\mu (6)(9.8)=(6-4)9.8+30\\\\\\mu=0.84"
