Question

Calculate the Potential Energy

Answer 1

There are 2 objects. one is 2kg, and the other is 10. They are 10m up

Answer 2

U=mgh

Answer 3

So I believe we would add the masses and multiply? @Data_LG2

Answer 4

yes, I believe so.

Answer 5

if it is so then it would be 120 then?

Answer 6

wait so we would multiply by gravity which is 9.8m/s?

Answer 7

Ep = (m1+m2)gh
Ep=( 2 kg + 10 kg) (9.8 m/s^2)(10)
Ep= ?

Answer 8

1176? question how would you like work out kg and m/s^2?

Answer 9

Ep=( 2 kg + 10 kg) (9.8 m/s^2)(10 m)
Ep = 1176 kg•m^2/s^2 or 1176 J

what do you mean by work out kg and m/s^2?

Answer 10

s: Like canceling out the terms idk how to say it

Answer 11

oh, you can't cancel the units. Just remember the definition of joule.
