A) \[4N\,\,s\]
B) \[8N\,\,s\]
C) \[32N\,\,s\]
D) \[192N\,\,s\]
Correct Answer: D
Solution :
Impulse \[=\] change in momentum \[=m(v-u)=0.12((-20)-12)\] \[=0.12\,\,(-32)=-3.84\,\,N\,\,s\] Force\[\text{=}\frac{\text{Change}\,\,\text{in}\,\,\text{momentum}}{\text{Time}}\] \[=\frac{3.84}{0.02}=192\,\,N\,\,s\]You need to login to perform this action.
