The "i" component of a vector is in the x-direction. Therefore, the x-component is 3 m/s.
Heya!!
For calculate aceleration, lets applicate second law of Newton:

<u>Δ Being Δ</u>
F = Force = 4 N
m = mass = 36 kg
a = Aceleration = ?
⇒ Let's replace according the formula:

⇒ Clear acceleration and resolve it:

Result:
The aceleration is of <u>0,111 meters per second squared (m/s²)</u>
Good Luck!!
Answer:
The Troposphere is the lowermost portion of Earth’s atmosphere. It is the densest layer of the atmosphere and contains approximately 75 percent of the mass of the atmosphere and almost all the water vapor and aerosol. The troposphere extends from the Earth’s surface up to the tropopause where the stratosphere begins.
