A) \[\frac{5}{8}\frac{{{u}^{2}}}{g}\]
B) \[\frac{3\sqrt{2}}{4}\frac{{{u}^{2}}}{g}\]
C) \[\frac{3\sqrt{3}}{8}\,\,\frac{{{u}^{2}}}{g}\]
D) \[2\sqrt{2}\frac{{{u}^{2}}}{g}\]
Correct Answer: C
Solution :
[c] \[2m{{v}_{x}}=mu+mu\,\,\cos 60{}^\circ \] |
\[{{v}_{x}}=\frac{3u}{4}\] |
Horizontal range after collision |
\[=\frac{3u}{4}\times \sqrt{\frac{2H}{g}}\] |
\[=\frac{3\sqrt{3}{{u}^{2}}}{8g}\] |
