Answer
The acceleration of the rocket is
.
Explanation
Acceleration is calculated as the change in velocity divided by the time over which this change occurs. The formula for acceleration (a) is:
where
is the change in velocity and
is the time.For this problem, the initial velocity (
) is
, and the final velocity (
) is
. The time (
) is 2 seconds. The change in velocity (
) is the final velocity minus the initial velocity:
Now we can plug these values into the acceleration formula:
