A) \[5\,\,kg\,\,m\,\,{{s}^{-1}}\]
B) \[10\,\,kg\,\,m\,\,{{s}^{-1}}\]
C) \[12\,\,kg\,\,m\,\,{{s}^{-1}}\]
D) \[14\,\,kg\,\,m\,\,{{s}^{-1}}\]
Correct Answer: C
Solution :
\[m=2kg;\,\,u=0;\,\,t=4\]seconds;\[a=1.5\,\,m\,\,{{s}^{-2}}\] \[v=u+at=0+1.5\times 4=6\,\,m\,\,{{s}^{-1}}\]. Gain in momentum\[=mv-mu\] \[=m(v-u)=2(6-0)=12\,\,kg\,\,m\,\,{{s}^{-1}}\].You need to login to perform this action.
