Part c
Based on the question I got the mass as 2.92 and the thrust as 33.4. 33.4 to match the exponent for both numbers. The answer I got when F/m=a is 33.4kg by m/s^2/2.92Kg=11.4m/s^2m/s^2. This is obviously wrong. What am I doing wrong?

g=10m/s^2
A fully loaded Saturn rocket has a mass of 2.92x10^6kg. Its engines have a thrust of 3.34x10^7N.
a) How much does the rocket weigh. answer 2.92x10^7 N
b) What is the net force on the rocket when it blasts off? answer 4.2x10^6N
c) What is the...
Thanks guys.
why would you average the rate?since the deceleration is uniform..u must not average
the rate.this shall lead to loss in generality of the problem.
This solved my question. I thought about it again and realized that I made an error. In any case, it will take me a while to...
I seem to have found the answer, but why is it that the rate is not averaged? The rate is going down from 65 to 0. Therefore, the rate should be an average before doing the calculations. I am confused.
