The car's final speed in m/s after the acceleration is 30.
<u />
<u>Given the following data:</u>
- Initial velocity, U = 0 m/s (since the cars starts from rest)
- Time, t = 10 seconds
- Acceleration, a = 3 meter per seconds square.
To find the car's final speed in m/s after the acceleration, we would use the first equation of motion;
Mathematically, the first equation of motion is given by the formula;
<em>Final speed, V </em><em>=</em><em> 30 m/s</em>
Therefore, the car's final speed in m/s after the acceleration is 30.
