Question
The NASA Space Launch System rocket that will carry the Artemis mission to the Moon travels 500 feet (152 m) straight up in the first 7 seconds of flight. It weighs 5.75 million pounds (mass of 2.61e6 kg).
In this problem, we'll calculate the acceleration and the net force on a similar rocket. The numbers will be randomized slightly for our question. Since the rocket is using fuel, this is an approximation anyway.

Expert Solution
Step 1

Solution:

Given that the initial speed of the rocket is zero and it reaches to 42.5 m/s in 8.80 seconds. Applying the kinematic equations to find the average acceleration. 

vy=uy+aytvy=0+aavg-gtvy=aavg-gtaavg-g=vytaavg=vyt+g=42.58.80+9.8  =14.63 m/s2
