According to the primary source what is the ultimate goal allied forces are hoping to achieve with this invasion?

unfortunately I'm not aware of which primary source you're talking about. I'm assuming youre writing about ww2?

Explanation:

The question says that, "After how long does a mobile acquire a speed of 30 m / s, if it starts from rest and its acceleration is 3 m / s*2"

Initial speed is 0

Final speed is 30 m/s

Acceleration a = 3 m/s²

It is required to find time when it acquire a speed of 30 m/s. Using equation of kinematics as :

So, after 10 seconds it will acquire a speed of 30 m/s.
