Question

If an air conditioning compressor weighing 300 lb had to be lifted 4 ft to be mounted on a base how many ft-lb of work must be accomplished

Answer 1

I think that would be m * g* h ft lbs

m = 300 , h = 4 and g is acceleration due to gravity ( 32 ft / sec^2)

Answer 2

simpler than that:

the \(MASS\) times gravity gives the \(WEIGHT\), which is 300lb. \(m*g\) is 300 lb already. No need to multiply by gravity again.

Answer 3

I took it to be the mass because the weight should have been given in Newtons.

Answer 4

since the weight is given in pounds, the distance given in feet, and the work done in foot-pounds, it's practically already solved
