A) 1000 \[km\,{{h}^{-1}}\] in the direction west to east
B) 1000 \[km\,{{h}^{-1}}\] in the direction east to west
C) 2000 \[km\,{{h}^{-1}}\] in the direction west to east
D) 2000 \[km\,{{h}^{-1}}\] in the direction east to west
Correct Answer: A
Solution :
[a] \[\vec{v}A=-500\hat{i}\]and \[\vec{v}GA=1500\hat{i}\] \[\Rightarrow \vec{v}GA+\vec{v}A=\vec{v}GAS\] \[\Rightarrow \vec{v}GAS=1500\hat{i}-500\hat{i}=1000\hat{i}\]You need to login to perform this action.
