A20%-efficient car engine accelerates the 1300 kg car from rest to 13 m/s. how much energy is transferred to the engine by burning gasoline?

The energy transferred to the engine by burning gasoline is 549250 J.

Explanation:

Given that,

Mass of car = 1300 kg

Speed = 13 m/s

We need to calculate the change in kinetic energy

Using formula of change in kinetic energy

Where, m = mass

v = speed

Put the value into the formula

We need to calculate the heat energy

Using formula of efficiency

Put the value into the formula

Hence, The energy transferred to the engine by burning gasoline is 549250 J.

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

another example of kinetic energy would be,

kinetic energy   >     moving energy
