Question
Mass 1 is sitting on mass 2 which is sitting on a frictionless surface. Between the masses, the coefficients of kinetic friction are known.
a) Draw FBDs of each object.
b) What is the max. force F that can be applied so that mass 1 does not slip on mass 2.
c) What is the corresponding aceleration of mass 2.
Express the answers in terms of the paramerters of the problem: the masses, the coefficients of friction.
d) Substitute the numbers: mass 1 is 10kg, mass 2 is 5kg, coefficient of kinetic friction is 0.2 and of static friction 0.4. (Ans. acc=1.57m/s^2
