A) 600 W
B) 300 W
C) 150 W
D) 75 W
Correct Answer: A
Solution :
Power of gun \[=\frac{\text{Total}\,\text{K}\text{.E}\text{.}\,\text{of}\,\text{fired}\,\text{bullet}}{\text{time}}\] \[=\frac{n\times \frac{1}{2}m{{v}^{2}}}{t}=\frac{360}{60}\times \frac{1}{2}\times 2\times {{10}^{-2}}\times {{(100)}^{2}}=600\,W\] Hence, the correction option is (a).You need to login to perform this action.
