If two objects collid and one is initially at rest, is it possible for both to be at rest after the collision?

Answer:
<em>Is it NOT possible for both particles to be at rest after the collision</em>
Explanation:
<u>Law Of Conservation Of Linear Momentum</u>
The total linear momentum of a system of particles is conserved regardless of their internal interactions while no external force is applied to the system. If and
are the masses of two particles, and only one of them is at rest, there is a non-zero total linear momentum, i.e.
if at least one of the speeds is not zero, the total initial linear momentum is not zero.
If after the collision, both particles remain at rest, both speeds will be zero and the total linear momentum won't be conserved.
So, is it NOT possible for both particles to be at rest after the collision

Answer:
A) Therefore if I double the masses with are in the two terrine they are simplified and the radii of the speeds remain the same
B) If the masses are maintained and the speeds are doubled, the radius of the two speeds remains the same
Explanation:
A vehicle crash problem must be solved with the equation of the moment,
Initial instant Before crash
p₀ = m v₁ + mv₂
After the crash
= m
+ m
p₀ =
If the speed ratio before and after the crash is one
p₀ / = 1
We can assume that initially one of the cars was stopped
m v₁₀ = m
v₁₀ =
For the two speeds to be equal, the masses of the vehicles must be the same.
A) Therefore if I double the masses with are in the two terrine they are simplified and the radii of the speeds remain the same
B) If the masses are maintained and the speeds are doubled, the radius of the two speeds remains the same
