Please help me...
A particle of mass m travelling with a velocity u makes a head-on elastic cpllision with another particle of mass M which is at rest. If m<M,show that the particles with mass m moves in the direction opposite to its initial velocity after collision.

Do you know how to derive this equation
$\huge\sf \boxed{u_2=\frac{m-M}{m+M}u_1}$

?

abhisar · Answer

From the above equation we can see that the final velocity v for an object of mass m will be

$\huge\sf \boxed{v=\frac{m-M}{m+M}u}$

Now if m<M, value of v will be negative which means the direction of v will be opposite to u

ok...Thanks....

Do you know how to derive the below equation which i used ?


$\huge\sf \boxed{u_2=\frac{m-M}{m+M}u_1}$

anonymous · Answer

don't know...

abhisar · Answer

Have u read ur books carefully ?

`Conservation of linear momentum` and `conservation of kinetic energy` in an elastic collision ?

anonymous · Answer

@Abhisar i know how to get it already...

abhisar · Answer

That's Great !...in case if u don't u can use this
