A) \[\frac{v}{2}\sqrt{1+2{{\cos }^{2}}\theta }\]
B) \[\frac{v}{2}\sqrt{1+2{{\cos }^{2}}\theta }\]
C) \[\frac{v}{2}\sqrt{1+3{{\cos }^{2}}\theta }\]
D) \[v\cos \theta \]
Correct Answer: C
Solution :
\[\text{Average}\,\text{velocity}\,\,\text{=}\,\,\frac{\text{Displacement}}{\text{Time}}\] \[v=\frac{\sqrt{{{H}^{2}}+\frac{{{R}^{2}}}{4}}}{\frac{T}{2}}\]You need to login to perform this action.
