(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

There are two blocks stacked on top of each other. M2 is on top of M1. M1 = 3 kg. m2 = 4 kg. μs between the two boxes = 0.6. μk between m2 and the floor = 0.2.

Using a rope, we exert a force T on m2, dragging both boxes 5m. What is the maximum force we can exert on m2, if we don't want m2 to slip on m1.

2. Relevant equations

Fk = μk * n

Fs(max) = μs * n

3. The attempt at a solution

I found Fs(max) between m2 and m1.

Fs(max) = n * μs =

mg * 0.6 =

4kg * 9.8 * 0.6 =

23.52 N.
