Question

A car starts from rest and reaches a speed of 12m/s in 20s. It's acceleration is

Answer 1

Given

A car starts from rest and reaches a speed of 12m/s in 20s.

To find

The acceleration

Step-by-step explanation

Using the equation of kinematics

`v=u+at`

where v is the final velocity

u is the initial velocity

a is the acceleration

t is the time.

Thus,

`\begin{gathered} 12=20a \\ \Rightarrow a=0.6m/s^2 \end{gathered}`

Conclusion

The acceleration is

`0.6m/s^2`
