Agallon of gasoline contains about 1.3 x 108joules
of energy. a 2000 kg car traveling at 20 m/s skids to astop.
estimate how much gasoline it will take to bring the car backto the
original speed? to complicate matters further, consider thefact
that only about 15% of the energy extracted from gasolineactually
propels the car. the rest gets exhausted as heat andunburnt
fuel.

The amount of gasoline is .

Explanation:

Given that,

Energy contained in gasoline

Mass = 2000 kg

Speed = 20 m/s

Energy used propel the car

We need to calculate the work done by the frictional force to stop the car

Using formula of work done

Therefore,

Work done to bring the car back to its original speed

Hence, The amount of gasoline is .
