Homework Statement
A small block is attached on the left of a larger block by a thin layer of grease, 2 micrometres (10^6) thick. The mass of the smaller block is 0.15 kg and the area of contact is 8x10^4 metres squared. If the smaller block slides down 5 mm in 2 weeks, calculate the viscosity of the grease. ANSWER: 9.07x10^5 Pa.s
Homework Equations
A formula which may help is Force/Area = Viscosity(change in velocity)/distances between areas of contact F/A = (n x delta v)/delta x
