In a dream you're in a car traveling at 50 km/h and you bump into another car traveling toward you at 48 km/h. The speed of impact is

2 km/h

To find the speed of impact, we need to calculate the relative velocity of the two cars. The relative velocity is the difference between the velocities of the two cars.

Given:
Velocity of the first car (your car) = 50 km/h
Velocity of the second car (the other car) = 48 km/h

To solve this problem, we'll subtract the velocity of the second car from the velocity of the first car:

Relative velocity = Velocity of the first car - Velocity of the second car

Relative velocity = 50 km/h - 48 km/h

Relative velocity = 2 km/h

Therefore, the speed of impact is 2 km/h.

To determine the speed of impact, we need to consider the relative velocities of the two cars. Since both cars are traveling towards each other, we need to add their speeds together.

In this case, one car is traveling at 50 km/h, while the other is traveling at 48 km/h. To find the combined speed, we add these two speeds together:

50 km/h + 48 km/h = 98 km/h

Therefore, the speed of impact between the two cars is 98 km/h.

50 + 48 = 98 km/h.
