Question

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)

Answer 1

The ultralight car weighs 910 kg less than the 1450-kg 2007 Honda Accord.

Step-by-step explanation:

To find out how much less an ultralight car weighs compared to a 2007 Honda Accord, we first state the weight of both vehicles. The ultralight car weighs 540 kg and the Honda Accord weighs 1450 kg. We then calculate the difference in weight:

Weight of Honda Accord - Weight of Ultralight Car = 1450 kg - 540 kg = 910 kg.

Therefore, the ultralight car weighs 910 kg less than the 2007 Honda Accord.

Answer 2

Then the difference of weight between the two cars are:

Δw = 14210 - 5292 = 8918 N

Step-by-step 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:

`w_(uc) = (540)(9.8)`

`w_(uc) = 5292 N`

And the Honda Accord's weight is:

`w_(HA) = (1450)(9.8)`

`w_(HA) = 14210 N`

Then the difference of weight between the two cars are:

Δw = 14210 - 5292 = 8918 N
