This question is driving me insane. I can't figure out how to do this unless you were given another value such as the coefficient of friction or just the efficiency. And as the system is in equilibrium, there is no resultant force, do you try to figure it out by imagining it without friction and finding what the acceleration would be ???????
AHSIHBDHKBEKDBDWBIWD this is very confusing. I might be missing something but I can't see it. sorry I can't help :/
