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 .

80.6 milliliters? O.o

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

but where did you get 9.8m/s2?

That's a lot of work... umm, it says nothing about "moving up against gravity" but if you say so... thanks, i guess. can you give me another example with this question -What is the mass of an object if it took 270 J of work to move it 15 meters?

Okay, thank you... I have another question If an object has a mass of 47 kg and it is moved 27 meters in 60 seconds, how much power was used? (also, would this also include the 9.8 from g?) Thanks.

Oh ok, thank you :)
