1. The problem statement, all variables and given/known data What is the acceleration when a 30.0 lb force acts on a 12.2 slug mass? 2. Relevant equations a=F/m 3. The attempt at a solution I can't quite figure out the slug thing. I took 12.2 slugs to be 392.5 lb/ft/s2 Then divided 30 by 392.5 lbs got cancelled out and I'm left with ft/s2 in denominator which the is reversed because we are dividing fractions ??? Is this right? I get 7.6 x 10 -2 ft/s2 Thanks a million!!!!
