A 5.8 x 104 kg train car at rest is struck from behind by a second train car, traveling at 2.6 m/s. The collision is completely inelastic so the cars stick together. The mass of the second car is 7.4 x 104 kg. What is the velocity of the joined trains cars immediately after the collision?
Round your answer to the tenths place.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

i don't know that i agree with that but what's the question ?

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
