With fuel prices for combustible engine automobiles increasing, researchers and manufacturers have given more attention to the concept of an ultralight car. using carbon composites, lighter steels, and plastics, a fuel-efficient car can be manufactured at 540 kg. how much less does an ultralight car weigh compared to a 1450-kg honda accord (2007)

Then the difference of weight between the two cars are:

Δw = 14210 - 5292 = 8918 N

Explanation:

An object's weigh due to the gravitational attraction force of the earth is:

w = mg

            Where: m is the object's mass

                         g is the  gravitational acceleration in the surface earth

                         g = 9.8 m/s2

The the ultralight car's weight is:

And the Honda Accord's weight is:

Then the difference of weight between the two cars are:

Δw = 14210 - 5292 = 8918 N
