Answer 2

## Step 1The first part of the problem involves matching the descriptions in Column A to the corresponding descriptions in Column B. ## Step 2An elastic collision is one in which both momentum and kinetic energy are conserved. This matches with description b in Column B.## Step 3An inelastic collision is one in which momentum is conserved but kinetic energy is not. This is typically due to the loss of kinetic energy in the form of heat or sound. This matches with description c in Column B.## Step 4Momentum is the amount of "oomph" a moving object has. This matches with description d in Column B.## Step 5Impulse is the change in momentum an object experiences in a collision. This matches with description a in Column B.## Step 6The second part of the problem involves understanding the concept of impulse and how it relates to collision time and force of impact.## Step 7Impulse is the change in momentum of an object when a force is applied over a period of time. The formula for impulse is

.## Step 8When object A lands on a foam cushion, the collision time is longer because the cushion compresses, absorbing the impact over a longer period of time. This results in a smaller force of impact.## Step 9When object B lands on concrete, the collision time is shorter because the concrete is hard and does not compress. This results in a larger force of impact.
