PLEASE SUBMIT A MODEL OF THE POTENTIAL AND KINETIC ENERGY OF A ROLLER COASTER. I need a model of the instructions above and below.
Create a model to examine the potential and kinetic energy of a roller coaster cart.
BASICALLY, I NEED A PICTURE DRAWN OF THE POTENTIAL AND KINETIC ENERGY THAT A ROLLER COASTER HAS WHEN GOING DOWN A SLOPE.

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende

What is the formula that this ionic compounds could form sr2+p3-o2-

Tin has ten stable isotopes. the heaviest, 124sn, makes up 5.80% of naturally occuring tin atoms. how many atoms of 124sn are present in 82.0 g of naturally occurring tin? what is the total mass of the 124sn atoms in this sample?
