You push a 2.0 kg block against a horizontal spring, compressing the spring by 14 cm. then you release the block, and the spring sends it sliding across a tabletop. it stops 84 cm from where you released it. the spring constant is 290 n/m. what is the coefficient of kinetic friction between the block and the table?

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
