An Intiative by Sri Chaitanya

$(12 \hat{i} + 10 \hat{j}) m / s, (10 \hat{i} + 7 \hat{j}) m$

$(10 \hat{i} + 7 \hat{j}) m / s, (12 \hat{i} + 10 \hat{j}) m$

$(20 \hat{i} - 10 \hat{j}) m / s, (10 \hat{i} - 7 \hat{j}) m$

$(10 \hat{i} - 7 \hat{j}) m / s, (12 \hat{i} - 10 \hat{j}) m$

answer is B.

Detailed Solution

$\vec{a} = (4 \hat{i} + 2 \hat{j}) m / s^{2}$

$\vec{v} = (2 \hat{i} + 3 \hat{j}) + (2) (4 \hat{i} + 2 \hat{j}) = (10 \hat{i} + 7 \hat{j}) m / s$

$\vec{s} = (2) (2 \hat{i} + 3 \hat{j}) + \frac{1}{2} (2)^{2} (4 \hat{i} + 2 \hat{j}) = (12 \hat{i} + 10 \hat{j}) m$
