Explanation:
An object moves with 5 m/s towards right while mirror moves with 1 m/s towards the left as shown. Find velocity of image.
(a)5m/stowardsright(b)7m/stowardsleft(c)7m/stowardsright(d)5m/stowardsleft
A)
Vi−Vm=Vm−V0
Vi−(−1)=(−1)−5
∴Vi=−7m/s
7 m/s and direction towards left
Hence b is the correct answer.
