A) \[\frac{1}{8}m/s\]
B) \[\frac{1}{4}(\sqrt{3}-1)m/s\]
C) \[\frac{1}{4}m/s\]
D) \[\frac{1}{8}(\sqrt{6}-\sqrt{2})m/s\]
Correct Answer: D
Solution :
\[v=\frac{1}{4}m/{{s}^{2}}\] Component of v along OB \[=\frac{\frac{1}{4}\sin {{30}^{o}}}{\sin ({{30}^{o}}+{{45}^{o}})}=\frac{\frac{1}{4}\sin {{30}^{o}}}{\sin {{75}^{o}}}\]You need to login to perform this action.
