CALCULATE: A roller coaster with a mass of 100 kilograms needs to be accelerated at 15m/s² along the track in order to move. How much force is
needed to move the coaster?

No bc a lot of things r still theories n unproven

Not what goes around on earth but the universe too.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
