Answer:
C
Explanation:
He was using visual clues to read the signs.
Answer:
Explanation:
Our values are
We can find the time through
The expression for the distance between the Earth and the spaceship is as follow:
Where c is Light speed, and t our previous time.
Therefore the distance between the Eath and the Spaceship is 
m
It's always a good idea to start with the definition of the thing you're trying to find.
This problem is just trying to find out whether you KNOW the definition of acceleration. You may know it, but you haven't used it yet.
Average acceleration = (change in velocity) divided by (total time).
Change in velocity = (end value) minus (start value)
Change in velocity = (20m/s) - 0
Change in velocity = 20 m/s
Time = 10 s
Average acceleration = (20m/s)/(10s)
Average acceleration = 2 m/s^2
