A) \[-3\,\,N\,\,s,\,\,3\,\,k\,\,N\]
B) \[-30\,\,N\,\,s,\,\,-3\,\,k\,\,N\]
C) \[-50\,\,N\,\,s,\,\,-5\,\,k\,\,N\]
D) \[-60\,\,N\,\,s,\,\,-6\,\,k\,\,N\]
Correct Answer: B
Solution :
Now, impulse \[I=mv-mu=m(v-u)\] \[=0.06(0-500)=-30\,\,N\,\,s\] If \[F\] is the average force of blow, then\[I=Ft\] \[F=\frac{I}{t}=\frac{-30}{0.01}=-3,000\,\,N=-3\,\,k\,\,N\]You need to login to perform this action.
