Charisma · Answer 1

Average acceleration is the change in velocity divided by an elapsed time. So, we can calculate it as follows:

acceleration = 5 - 0 / 10 - 0 = 0.5 kilometers/second^2

Therefore the correct answer is option D.

Hope this answers the question. Have a nice day.

Ming · Answer 2

Average acceleration = (change in speed) / (time for the change)

The missile's change in speed is (5,000 - 0) = 5,000 m/s

Average acceleration = (5,000 m/s) / (10 sec)

= 500 m/s² (about 51 Gs)
