a 5kg chunk of ice is sliding at 12m/s on the floor of an ice-covered valley when it collides and sticks to another identical chunk of ice that is initially at rest. Assume that the ice surface is frictionless. After the collision, the ice blocks slide partially up a hillside and then slide back down. How fast are they moving when they reach the valley floor again? (Hints: break down this problem into two parts - the collision and the behavior after the collision)

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

at right angles to each other
