´To develop this problem we will use the concepts related to the conservation of momentum and the application of energy conservation equations to find the velocity of the mass after the collision, like this:
Velocity of the mass
just before the collision



Therefore the momentum just before collision would be

Momentum after the collision

Since the momentum is conserved we have that



The velocity of mass
after the collision is given by



Therefore the change in momentum of mass 2 is



Therefore the impulse acting on m2 during the collision between the two boxes is 
The lists from greatest to lowest change in velocity.Dustin → Diego → Kira. Option A is correct.
<h3 /><h3>What is acceleration?</h3>
The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The acceleration is obtained one by one from the given data as the ratio of the velocity to the time.
For the acceleration of each, you can refer to the excel table attached below.
The velocity changes are listed from largest to least. Dustin and Diego Kira.
Hence, option A is the right answer.

Answer:
Light waves slow down as they travel from gas to solid.
Explanation:
The speed of light is often quoted with reference to a vacuum. Light travels fastest in a vacuum and in a gas.
When light travels through other media such as solids or liquids, the speed of light is decreased due to absorption and scattering of photons by molecules as well as remissions.
Hence the speed of light decreases from gas to solid.
