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?
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?
