Two stacked blocks are pushed along a horizontal table.
Force F' is applied horizontally to the 6m block as shown:
5m
6m
Assume there is kinetic friction at the interface between the 6m block and the table, and static friction at the interface between the two blocks.
If m = 2 kg, μs = 0.61, and μk = 0.36, what is the maximum force F' that can be exerted without the top block slipping?
Express your answer in N, to at least one digit after the decimal point.
