Answer:
The speed of the car 6 s after starting to move is 12 m/s.
Explanation:
A car started from rest and moved along a straight road with constant acceleration of [tex]2\ m/s^2[/tex] for 6 seconds.
It is required to find the speed of the car 6 s after starting to move. Let v is the final speed of the car.
The relation between speed, acceleration and time is given by :
[tex]v=u+at[/tex]
u = 0
[tex]v=at\\\\v=2\ m/s^2\times 6\ s\\\\v=12\ m/s[/tex]
So, the speed of the car 6 s after starting to move is 12 m/s.
