In a $1-$D elastic head$-$on collision, if the masses are equal and the second object is at rest, what can be said for the final speed of the objects after the collision?

$($There can be more than one answer$)$

Second object has more speed than that of first one.

Both objects have the wame speed.

First object stops and second object has whole speed of first one.

First object continues with the initiat speed white second object stops.

Total kinetic energy is not conserved.

Totar Knetic energy is conserved.
