hey guys, i was wondering if you could please help me
question:
The coefficient of static friction is 0.60 between the two blocks in figure. The coefficient of kinetic friction between the lower block and the floor is 0.20. Force F_vec causes both blocks to cross a distance of 5.0 m, starting from rest.What is the least amount of time in which this motion can be completed without the top block sliding on the lower block?
this is a very tricky question
force of friction for lower block: Ff= 13.72N
Fsmax= 23.52
so the force being exerted has to have a max of 9.8N
F=ma
9.8= 7a
a=1.4 m/s^2
i have no idea how i can get the time from this
