The following table shows the altitude and upward velocity of a Saturn V rocket

Question

The following table shows the altitude and upward velocity of a Saturn V rocket in the first 20 seconds of a launch. Use its data to complete the next three questions.

1) Is the rocket accelerating? How can you tell?

2)

What is the rocket's average acceleration during the first 20 seconds of flight?

Round your answer to the first decimal place.Your answer needs to be in units of m/s2

3)Use the average acceleration calculation to estimate the rocket's altitude at the 20 second mark.

Saturn V Launch time velocity 0 0 1 3 2 4 3 7 4 10 5 12 6 15 7 16 8 20 9 23 10 25 11 27 12 31 13 34 14 36 15 39 16 43 17 46 18 49 19 53 20 56

Explanation / Answer

1) a)Yes, it is evident that the rocket is accelerating because its speed increases in each entry.

2) average acceleration = average velocity/average time = 549/210 = 2.6 m/s^2

3) Altitude = 56*20 = 1120 m
