A) \[200N\]
B) \[500N\]
C) \[1000N\]
D) \[600N\]
Correct Answer: C
Solution :
According to work energy theorem, loss in kinetic energy \[=F\times S\] Since, finally the bullet stops, the loss in kinetic energy \[=F\times S\] Since, finally the bullet stops, therefore loss in kinetic energy = initial kinetic energy. or \[\frac{1}{2}m{{v}^{2}}=F\times S\] or \[\frac{1}{2}\times 10\times {{10}^{-3}}\times 100=F\times 5\times {{10}^{-2}}\] or \[F=1000\,\,N\]You need to login to perform this action.
