A854 kg car is traveling at 18.1 m/s. the driver wishes to go faster, so he pushes down on the gas pedal, and a force of 1260 n acts on the car to speed it up. after 4.1 s, how many meters per second will the car be traveling at? round your answer to the nearest tenth.

The car will be traveling at 24.2 m\s.

Explanation:

The first relationship we can estabilish between the measures is:

In which F, in N, is the force, m in kg is the mass and a is the accelation.

In this problem, we have that:

So

We also can relate the speed to the accelaration, by the following formula:

In which v is the speed, is the initial speed, a is the acceleration and t is the time.

We have that,

So:

The car will be traveling at 24.2 m\s.

developed countries have tended to improve the environment, while developing countries have tended to damage it.
