A) \[({{v}_{1}}+{{v}_{2}})\]
B) \[({{v}_{1}}+{{v}_{2}})/2\]
C) \[({{v}_{1}}+{{v}_{2}})/3\]
D) \[(2{{v}_{1}}+3{{v}_{2}})/3\]
Correct Answer: B
Solution :
If the particle moved with velocity\[{{v}_{1}}\]for time \[{{t}_{0}},\]then total time of motion\[=2{{t}_{0}}\] . The average velocity is \[=\frac{displacement}{time}=\frac{{{v}_{1}}{{t}_{0}}+{{v}_{2}}{{t}_{0}}}{2{{t}_{0}}}\]You need to login to perform this action.
