Answer:
0.68 s
Explanation:
We are given that 
Initial velocity of box=
Final velocity of box=v=11.5 m/s
Distance=d=8.5 m
We have to find the time taken by box to slow by this amount.
We know that 

Substitute the values 




We know that 
Acceleration=
Substitute the values 



Hence, the time taken by box to slow by this amount=0.68 s
