1. The problem statement, all variables and given/known data What minimum horsepower must a motor have to be able to drag a 270 kg box along a level floor at a speed of 1.20 m/s if the coefficient of friction is 0.50? 2. Relevant equations Ffr=mu*mg W=Ffr*d 3. The attempt at a solution I ended up having W=Fr*d=mu*m*g*d (.5)*(270)*(1.2)*(1.2)=194.4 J/s=.26 hp That is way too low. Can anyone give me any guidance?
