if it takes 726 watts of power to move a mass 36 meters in 14 seeconds, what is the mass?
i really need like, step by step help please? asap.
thanks, michelle .

power= work/time= mass*g*distance/time
mass= power*time/distance*g

so... would it be like,
726 x 14 / 36 ?

no, what happened to g (9.8m/s^2) in the denominator?

physics 
michelle quendarsv
but where did you get 9.8m/s2?
