the maximum displacement in an oscillatory motion is A=0.49m . determine the position x at which the kinetic energy of the particle is half its elastic potential energy (if KE=U/2 x=!)

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?
