A space shuttle is launched into space. During the first \[8\] minutes of its launch the average acceleration of the shuttle is\[17.5\,\,m\,\,{{s}^{-2}}\]. |
A) \[8000\,\,m\,\,{{s}^{-1}}\]
B) \[8400\,\,m\,\,{{s}^{-1}}\]
C) \[1200\,\,m\,\,{{s}^{-1}}\]
D) \[1500\,\,m\,\,{{s}^{-1}}\]
Correct Answer: B
Solution :
\[v=u+at=0+17.5\times (8\times 60)\] \[=8400\,\,m\,\,{{s}^{-1}}\]You need to login to perform this action.
