Question

I WILL MARK YOU AS BRAINLIEST IF U ANSWER THIS QUESTION...............................A mirror is moving with a velocity of 3m/s.an object is moving along the direction of mirror with 4m/s.what is the velocity of object w.r.t the image?

Answer 1

the answer is 4+3=7m/s^2


plz mark as brainliest ander.

Answer 2

hey mate your answer plz mark as brainlist if ihas correct

The distance of the virtual image formed in the plane mirror is the (-) distance of the object from the mirror=> if the distance of the object from the mirror=x =>that of the virtual image from mirror surface =-x.So if the speed of the observer changes wrt mirror ie (dx/dt)=>its image will also move at a speed =d(-x)/dt=(-)dx/dt art mirror. dx/dt=2 m/s,so the speed of image wrt mirror surface=(-)2 m/s.Which indicates to the relative speed of image wrt the speed of observer=2-(-2)=4m/s.Ans..
