Bike running at 90 km per hour is slowed down to 54 km per hour by the application of brakes over a distance of 40 m calculate the total time in which the bike to comes to rest and the total distance travelled by bike

10 is the . . .

The correct answer is c. hope this

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.
