What is the impact speed when a car moving at 114.0 km/h bumps into the rear of another car traveling in the same direction at 104.5 km/h?

114 - 104.5

9.5

To determine the impact speed when a car bumps into the rear of another car, you need to calculate the relative velocity between the two cars.

The relative velocity is the difference between the velocities of the two cars since they are traveling in the same direction.

Given:
Velocity of the first car (car 1) = 114.0 km/h
Velocity of the second car (car 2) = 104.5 km/h

To calculate the relative velocity, subtract the velocity of car 2 from the velocity of car 1:

Relative velocity = Velocity of car 1 - Velocity of car 2
= 114.0 km/h - 104.5 km/h
= 9.5 km/h

Therefore, the impact speed when the car bumps into the rear of the other car is 9.5 km/h.
