A) 10 units
B) \[7\sqrt{2}\] units
C) 7 units
D) 8.5 units.
Correct Answer: B
Solution :
\[\overrightarrow{V}=\overrightarrow{u}+\overrightarrow{at}\] \[\overrightarrow{V}=(3\hat{i}+4\hat{j})+10(0.4\hat{i}+0.3\hat{j})\] \[\overrightarrow{V}=7\widehat{i}+7\hat{j}\] \[\Rightarrow \] \[|\overrightarrow{V}|=7\sqrt{2}\]You need to login to perform this action.
