I did 25m/ 2.5s which is 10 m/s. not exactly sure tho
Answer:
The net force on the car is 2560 N.
Explanation:
According to work energy theorem, the amount of work done is equal to the change of kinetic energy by an object. If '' be the work done on an object to change its kinetic energy from an initial value '' to the final value '', then mathematically,
where '' is the mass of the object and '' and '' be the initial and final velocity of the object respectively. If '' be the net force applied on the car, as per given problem, and '' is the displacement occurs then we can write,
Given, .
Equating equations (I) and (II),
In addition to ozone, the four other greenhouse gases or groups of greenhouse gases are included in nearly all the climate models are Carbon dioxide, water vapor, and methane, nitrous oxide.
Carbon dioxide, absorbs energy at a variety of wavelengths, a range that overlaps with that of infrared energy. As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions. About half of that energy goes out into space, and about half of it returns to Earth as heat, contributing to the ‘greenhouse effect.’
As methane is emitted into the air, it reacts in several ways. It reacts and after oxidization methane forms water vapor and carbon dioxide. So, not only does methane contribute to global warming directly but also, indirectly through the release of carbon dioxide.
Nitrous oxide enhances the greenhouse effect by capturing reradiated infrared radiation from the Earth’s surface and subsequently warming the troposphere . It is chemically inert in the troposphere and stays in the troposphere for about 120 years before moving into the stratosphere where it ultimately leads to destruction of stratospheric ozone.
Water vapor does absorb longwave radiation and radiates it back to the surface, thus contributing to warming.
