An object moves with \( 5 \mathrm{~m} / \mathrm{s} \) towards right while the mirror moves with \( 1 \mathrm{~m} / \mathrm{s} \) towards the left. Find the velocity of image.
(a) \( 2 \mathrm{~m} / \mathrm{s} \) right
(b) \( 2 \mathrm{~m} / \mathrm{s} \) left
(c) \( 7 \mathrm{~m} / \mathrm{s} \) right
(d) \( 7 \mathrm{~m} / \mathrm{s} \mathrm{left} \)
