Answer:

Collision force will be same in both the cases.

Explanation:

A perfectly inelastic collision is said to take place when a system loses the amount of its Kinetic Energy at its maximum. In a perfectly inelastic collision, the colliding particles stick to each other. In such a collision, kinetic energy is lost by combining the two bodies with each other.

In situation 1:

Speed of Car A, $v_{A} = 10 mph$

Speed of Car B, $v_{B} = 20 mph$

Relative speed of car A and car B, $v = v_{b} - v_{a} = 10 m/s$

Now, in the situation 2:

Speed of car A, $v_{A} = 30 mph$

Speed of car B, $v_{B} = 40 mph$

Relative speed of car A and car B, $v = v_{b} - v_{a} = 10 m/s$

Therefore, Car A and Car B both have the same relative speed, v = 10 m/s

The level of water in an olympic size swimming pool (50.0 meters long, 25.0 meters wide, and about 2.00 meters deep) needs to be

Goshia [24]

<span>We need to start by finding the surface area of the pool.
50 meters multiplied by 25 meters gives us 1250 square meters.
1250 square meters multiplied by .065 (6.5 cm in meters) gives us a volume of 81.25 cubic meters of water that needs to be pumped out of the pool.

There are 1000 liters in a cubic meter so this is 81250 liters. Divide by 4.2 to find the number of seconds required to pump out this much water and we get 19345.2 seconds. This equals approximately 5.37 hours.</span>
