How do the molecules at point A compare to the molecules at point B?

the plateau is likely to turn into a desert do to corrosion.

pe = weightxheight = 2000x1000=2,000,000joules

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer
