Quote" Napoleon's army captured the island of San Salvador, then moved on to occupy Louisiana and close the port of New Orleans."
Remember what acceleration is? It's how fast the speed is changing over a period of time.

So in dt = 2 secs, she sped up from 6 to 10 m/s and so dv = (10-6) m/s.
Now that you know dv and dt, you can calculate the acceleration a!
'First Quarter' is the phase that appears one quarter of the
period of time from one new moon to the next one.
The total period of the moon's phases is 29.53 days (rounded).
One quarter of it is (29.53 / 4) = <em>7 days 9.2 hours</em> (rounded)
