To determine which object will reach the bottom of the ramp first, we will need to know their speeds at the bottom of the ramp. The object which moves faster when reaching the bottom of the ramp will also be the one who gets there first. Use the equation that we found in the preceding question to solve for the speed (v).

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.

Two cars collide, lock bumpers and move together after the collision.this collision is known as perfectly inelastic collision.

It is increased due to the doppler effect. (apex)
