Answer:
It takes 
to accelerate the object from rest to the speed v.
Explanation:
From Newton's second law:
(1)
and the definition of acceleration,
(2)
we can solve this problem. Putting (2) in (1) we have:
and solving for 
and considering the initial time as zero (
) and the initial velocity also zero (
) we have:
Now, for a mass 
and the 
we can wrtie the same equation:
and substituting 
and 
:
So now, it only takes half the time to accelerate the object from rest to the speed v
