If you drive your 1000 kg car from sea level up to the Nu’uanu Pali lookout,which is 366m above sea level, how much will you have increased your car’s potential energy?

Blacklash

Answer:

The height of the cliff in meters = 27.44

Explanation:

 The potential energy of a body is given by the expression, PE = mgh, where m is the mass of the body, g is the acceleration due to gravity value and h is the height of the body.

 Here we have mass of car = 1000 kg

                          Height of car = 366 m

                          Acceleration due to gravity  = [tex]9.81m/s^2[/tex]

                          Substituting   PE = 1000 * 9.81 * 366

                                                      PE = 3590460 J = 3590.46 kJ

      Increase in car’s potential energy = 3590.46 kJ
