Homework Statement
What is the largest force F that can be applied to the large block such that the small block doesn't slide off.
There are two blocks of M1=10kg, M2=20kg. M1 is on top of M2, M2 is on top of the table.
the coefficients of static and kinetic friction between the two blocks, and also between the large block and the table are [tex]\mu[/tex]s=.2, [tex]\mu[/tex]k=.1 respectively. let g=10m/s^2
Homework Equations
The Attempt at a Solution
Well, i thought that simply that the force should be applied to where the force of friction would be the max of static friction, so F=-Ff=.2(10kg)(10m/s^2)= 20N
It seems wrong, but I can't figure out what is.
