.An object moving at a speed of 5m/s towards a concave mirror of focal...
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​=101​m


Average speed of image =(Distance moved by image)/time


=1/10m/s
