Given,
Focal length, f=−1m
Object distance, u=−9m
Image distance, v=?
We know that
f1=u1+v1
−11=−91−v1
v1=9−10
v=10−9
Negative sign indicates that it is on the left side of the mirror.
Consider a time of 1 second.
Object distance =5m/s
Hence, Distance=Speed×Time=5×1=5m is travelled by object in 1 second
So, u=9−5=4m
Now, we need to find the new image distance using the formula
f1=u1+v1
−11=−41+−v1
v=5−4
Negative sign indicates that it is on the left side of the mirror.
Change in image distance =10−9−5−4=101m
Average speed of image =(Distance moved by image)/time
=1/10m/s
