i do not have an answer because it depends on the size and the distance lol
 
        
             
        
        
        
Answer:
<h2>
 m/s ^2
 m/s ^2</h2><h2 />
Explanation:
Solution,
When a certain object comes in motion from rest, in the case, initial velocity = 0 m/s
Initial velocity ( u ) = 0 m/s
Final velocity ( v ) = 72 km/h ( Given)
We have to convert 72 km /h in  m/s


 m/s
 m/s
Final velocity ( v ) = 20 m/s
Time taken ( t ) = 2 seconds
Acceleration (a) = ?
Now,
we have,



 m/s ^2
 m/s ^2
Hope this helps...
