Haha, yeah I'm really sorry about that. To be honest, I'm not really sure of the units on anything except the initial numbers. That said for the gravitational force I multiplied NM^2/kg^2 by kg by kg divided by km, whatever that comes out to. I guess the acceleration would be m/s^2. Is it...
I've been working on this question for a couple hours now and I can't seem to get a different answer. Is it possible that the answer given in the study guide is incorrect?
Homework Statement
A 600kg satellite moving in a stable circular orbit about the Earth at a height of 4000km (G=6.67x10^-11 NM^2/kg^2, Re=6380km, Me=5.98x10^24kg).
Calculate the speed of the satellite at that height.
Calculate the orbital period (T), the time for one revolution
Calculate...
Thank you so much for your help.
from bernoulli's I get to .5(d)(v1sqrd)=P2-P1. Once I plug in my numbers: .5(1.293)(576)=372.384. Then multiplied by the area: 372.384(300)= 111715.2 N/msqrd. For some reason the study sheet has the answer as 108000 N/msqrd, but maybe this could just be...
Homework Statement
If wind blows at 24 m/s over your house, what is the net force on the roof if its area is 300 m squared?
