Answer 1

Hi!

I am an IIT JEE ASPIRANT

And all India mathematics OLYMPIAD TOPPER in class 10th

It's too simple question

You will not get such answers from anyone

Mirror at an angle x

Now it's common that v cosx component of particle is parallel to mirror,

So, this component will not change

Also,

V sinx component is perpendicular to the mirror so it will change its direction only because mirror is at rest

Velocity of particle = V cosx j + V sinx i

Velocity of image = V cosx j - V sinx i

So resultant velocity = V making angle 90° - x with mirror

Answer 2

Mirror at an angle x

Now it's common that v cosx component of particle is parallel to mirror,

Also,

V sinx component is perpendicular to the mirror so it will change its direction only because mirror is at rest

Velocity of particle = V cosx j + V sinx i

Velocity of image = V cosx j - V sinx i

So resultant velocity = V making angle 90° - x with mirror..
