I have a question I dont understnad 3. A student approaches a plane mirror at a speed of 2 m/s. a) at what speed does her image approaches the mirror? b) at what speed does she approach her image? and another one ... If a toddler crawls towards a mirror at a rate of 0.25 m/s, then at what speed will the toddler and the toddler's image approach each other? the answer was 0.5m/s but why???
its just like you and another guy running towards each other at the same individual speed you are running at 2 m/s and so is he so the combined speed is 4 m/s
Because both the object and the image are moving toward one another;
so you have 3 (a) 2 m/s (b) 2+2 = 4 m/s
