Is this a question or a statement. This statement would be incorrect. <span />
Boyle's law and Charles's law tells us that the volume of a gas is dependent on pressure and temperature. That is why scientists have to also take measurements of the pressure and temperature when they take the measurement for volume of the gas.
Explanation:
the force exerted from by the car on the wall Is contact force
the force exerted by the wall on the car i don't know
60 ° is the angle between W- direction and the run direction.
You need the angle betwee S-direction and the run direction. This is 90° - 60° = 30 °.
By geometry you can trace a right triangle, where the S-component is the adyacent side and the run is the hypotenuse.
Then cos 30° = adyacent side / hypotenuse = S-component / run
Then S-component = run * cos 30° = 5.0 km * 0.866 = 4.3 km
Answer: 4.3 km
