A) 5h
B) \[5\sqrt{2}\,\,h\]
C) \[10\sqrt{2}\,h\]
D) 0 h
Correct Answer: A
Solution :
\[{{V}_{A}}=10\left( -\widehat{i} \right)\] \[{{V}_{B}}=10\left( -\widehat{j} \right)\] \[{{V}_{BA}}=10\widehat{j}+10\widehat{i}\] \[=10\sqrt{2}\text{ km/h}\] \[\text{Distance OB=100 cos45}{}^\circ \] \[\text{=50}\sqrt{2}\text{ km}\]You need to login to perform this action.
