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.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

option number c is the right answer.
