A) \[120\,\,m\,\,{{s}^{-1}}\]
B) \[240\,\,m\,\,{{s}^{-1}}\]
C) \[360\,\,m\,\,{{s}^{-1}}\]
D) \[480\,\,m\,\,{{s}^{-1}}\]
Correct Answer: B
Solution :
Mass of man\[(m)=60\,\,kg\] Velocity of man walking\[=4\,\,m\,\,{{s}^{-1}}\] Momentum \[=\] mass \[\times \] velocity \[=60\times 4=240\,\,m\,\,{{s}^{-1}}\]You need to login to perform this action.
