PLSSS HELP A 2-kg cart starting from rest rolls down a hill and at the bottom has a speed of 5 m/s . If the cart were given an initial push, so its initial speed at the top of the hill was 2 m/s , what would be its final velocity at the bottom?

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

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.
