A particle is moving with velocity $(\hat{i} + 2 \hat{j} + 3 \hat{k}) m / s$ . A plane mirror exists in the x-y plane. The mirror has a velocity $(\hat{i} + 2 \hat{j}) m / s$ . Velocity of the image (in m/s) is:

Options:

Answer:

Solution:

$v_{p} = v_{f} + v_{n}$

$v_{I} = v_{f} - v_{n}$

$v_{f} = \hat{i} + 2 \hat{j}$

$v_{n} = 3 \hat{k}$

$v_{I} = \hat{i} + 2 \hat{j} - 3 \hat{k}$
