Answer» `3xx10^(-4)` `3xx10^(23)` `3xx10^(-6)` `3xx10^(-7)` Solution :(a) Angular SPEED of `S_(2)` as observed by astronaut in `S_(1)`. `omega_(r )=(\|v_(1)-v_(2)\|)/(\|r_(2)-r_(1)\|)` `\|v_(1)-v_(2)\|=(2pixx10^(4)-pixx10^(4))km//h` `or \|v_(1)-v_(2)\|=(pixx10^(4)xx1000)/(60xx60)m//s` `or \|v_(1)-v_(2)\|=(3.14xx10^(5))/(36)=0.0872xx10^(5)=8.72xx10^(3) m//s` `\|r_(2)-r_(1)\|=3xx10^(7) m` `:. omega_(r )=(8.72xx10^(3))/(3xx10^(7))=2.9xx10^(-4)~~3xx10^(-4) rad//sec` `:. omega_(r )=3xx10^(-4) rad//sec.`
