A 1210 kg car is driving NE (at 45.0°) at 15.2 m/s when it is struck by a moving 1540 kg car. Afterwards, they stick together and move directly east (at 0°) at 23.3 m/s. What is the y-component of the second car's initial velocity?

Which of the following is a false statement about dispersion forces? view available hint(s) which of the following is a false statement about dispersion forces? dispersion forces are the result of fluctuations in the electron distribution within molecules or atoms. dispersion forces are present in all atoms and molecules. dispersion forces result from the formation of instantaneous dipoles in a molecule or atom. dispersion forces always have a greater magnitude in molecules with a greater molar mass. dispersion force magnitude depends on the amount of surface area available for interactions.
