A) 0
B) \[{{3}^{n}}\]
C) \[{{5}^{n}}\]
D) None of these
Correct Answer: A
Solution :
The general term of the series is \[-h=-u{{t}_{2}}+\frac{1}{2}gt_{2}^{2}\] \[0=u({{t}_{2}}-{{t}_{1}})+\frac{1}{2}g(t_{1}^{2}-t_{2}^{2})\] \[u=\frac{1}{2}g({{t}_{1}}+{{t}_{2}})\] Sum of the series is given by \[h=\frac{g{{t}_{1}}{{t}_{2}}}{2}\] \[\sqrt{2}\,mv\] \[\sqrt{2}\,mv'=(2m)\,v\] \[\Rightarrow \]You need to login to perform this action.
