( overset arrow v)I=-( overset arrow v)o+2( overset arrow v)m=-0+2(10)=20cms- 1

Q. A plane mirror is approaching you with $10 c m s^{- 1}$ you can see your image in it. At what speed will your image approach you ?

$10 c m s^{- 1}$

$15 c m s^{- 1}$

$20 c m s^{- 1}$

$25 c m s^{- 1}$

$(v \to)_{I} = - (v \to)_{o} + 2 (v \to)_{m} = - 0 + 2 (10) = 20 c m s^{- 1}$
