A) \[\frac{1}{2}\,m{{v}^{3}}\]
B) \[m{{v}^{3}}\]
C) \[\frac{1}{2}m{{v}^{2}}\]
D) \[\frac{1}{2}{{m}^{2}}{{v}^{2}}\]
Correct Answer: A
Solution :
| Let m is the mass per unit length then rate of mx mass per \[\sec =\frac{mx}{t}=mv\] |
| Rate of \[KE=\frac{1}{2}(mv)\,{{v}^{2}}=\frac{1}{2}\,m{{v}^{3}}\] |
