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,
Speed of Car B,
Relative speed of car A and car B,
Now, in the situation 2:
Speed of car A,
Speed of car B,
Relative speed of car A and car B,
Therefore, Car A and Car B both have the same relative speed, v = 10 m/s
To develop this problem it is necessary to apply the concepts related to the kinematic equations of motion. And from the speed found the relationships between wavelength, frequency and last of the period (which is inversely proportional to the frequency)
PART A) We know that the velocity of a body or a wave is equivalent to the distance traveled over a time interval. So,
Where
x = Distance
t = time
PART B) The frequency would then be defined as
Where
PART C) Finally the period is defined as
