A) 7 unit
B) \[7\sqrt{2}\] unit
C) 8.5 unit
D) 10 unit
Correct Answer: B
Solution :
From first equation of motion \[v=u+at\] \[v=3\mathbf{\hat{i}}+4\mathbf{\hat{j}}+10(,4\mathbf{\hat{i}}+0.3\widehat{\mathbf{j}})\] \[v=7\mathbf{\hat{i}}+7\mathbf{\hat{j}}\] \[|v|=7\sqrt{2}.\]You need to login to perform this action.
