A force on an object of mass 100 g is $(10 \hat{i} + 5 \hat{j})$ N. The position of that object at t = 2 s is $(a \hat{i} + b \hat{j})$ m after starting from rest. The value of $\frac{a}{b}$ will be ___________.

Accepted Answer

$\vec{F} = m \vec{a}$

$\Rightarrow \vec{a} = 100 \hat{i} + 50 \hat{j}$

So, $\vec{S} = \frac{1}{2} \vec{a} t^{2}$

$\frac{1}{2} (100 \hat{i} + 50 \hat{j}) 2^{2}$

$= 200 \hat{i} + 100 \hat{j}$ m

so a = 200 m and b = 100 m

so $\frac{a}{b} = 2$
