Question
In the sandwich below, the mustard has a viscosity of 50,000 cP, and the tomato paste has a 150,000 cP. The mustard layer has a thickness of 3.00 mm and the tomato paste layer has a thickness of 2.00 mm. The entire sandwich is 10 cm long and extends 10 cm in the direction perpendicular to the page. With the bottom cracker held in place, a 5.00 N dyne force is applied to the upper cracker. Find the speed of the upper cracker and the speed of the cheese. Any free body diagrams in your solution should follow the steps demonstrated in class.Explanation / Answer
hint use newton's law of viscosity
shear stress =viscosity*velocity gradient(del U/del Y)
U=velocity
Y=dstance btween plates
draw FBD and solve th equations
