Question

Two cars $A$ and $B$ move in the same direction with velocities $V_A=20\hat{i}\mathrm{~m} / \mathrm{s}$ and $V_B=15\hat{i}\mathrm{~m} / \mathrm{s}$. Then the relative velocity of $A$ with respect to $B$ is

Professor PC Thomas Classes · Answer

$V_{AB} = V_A - V_B = 20\hat{i} - 15\hat{i} = 5\hat{i} 	ext{ m/s}$.
