Answer:
The distance to the moon greater than the distance across the Atlantic ocean by an order of 1.
Explanation:
We have the average distance across the Atlantic ocean,
the average distance to the moon,
The factor by which the distance to moon is greater than the width of Atlantic ocean:
i.e.
the distance to the moon greater than the distance across the Atlantic ocean by an order of 1.
Answer:
Explanation:
The work done on the object at rest is all converted into kinetic energy, so we can write
Or, re-arranging for v,
where
v is the final speed of the object
W is the work done
m is the object's mass
If the work done on the object is doubled, we have W' = 2W. Substituting into the previous formula, we can find the new final speed of the object:
So, the new speed of the object is .
