A) \[9\sqrt{2}\] units
B) \[5\sqrt{2}\] units
C) 5 units
D) 9 units
Correct Answer: B
Solution :
| From the equation of motion, we knows |
| \[\mathbf{v}=\mathbf{u}=\mathbf{a}t\] Given, |
| \[\mathbf{v}=(2\mathbf{i}+3\mathbf{j})\] and \[\mathbf{a}=(0.3\mathbf{i}+0.2\mathbf{j})\] |
| \[\mathbf{v}=(2\mathbf{i}+3\mathbf{j})+(0.3\mathbf{i}+0.2\mathbf{j})\times 10\] |
| \[\mathbf{v}=5\mathbf{i}+5\mathbf{j}\] \[(\because v=u+at)\] |
| \[v=5\sqrt{2}\] units |
