The potential energy of an object is jointly related with the mass of the object and the height of the object. a 40-kg object is 2
meters off the ground. the potential energy of the object is 784 joules. a 10-kg object is 3 meters off the ground. what is the
potential energy of the 10-kg object?

294 Joules.

Step-by-step explanation:

For this all you have to do is use the equation for PE or Potential Energy. Which is given by ... PE = mgh.

m = the mass in kg

g  = the accerlation due to gravity (9.8 m/s^2)

h  = the height of the object in meters.

so... 10 kg (9.8)(3m) = 294 J

the answer is a

step-by-step explanation:

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
