Given
A car starts from rest and reaches a speed of 12m/s in 20s.
To find
The acceleration
Explanation
Using the equation of kinematics
[tex]v=u+at[/tex]where v is the final velocity
u is the initial velocity
a is the acceleration
t is the time.
Thus,
[tex]\begin{gathered} 12=20a \\ \Rightarrow a=0.6m/s^2 \end{gathered}[/tex]Conclusion
The acceleration is
[tex]0.6m/s^2[/tex]
