What else can I help you with?
The speedometer of a car moving to the east reads 100km per hr and it passes another car that moves to the west at 100km per hr so do both cars have the same speed please explain?
This is an ideal vehicle for explaining the concept of frame of reference. The speed of each car depends upon the frame of reference from which you measure it. If you take a stationary position at either car's starting point, you will measure the speed of the car coming toward you at 100 km/hr. You will also measure the speed of the approaching car at 100 km/hr. So relative to the ground they are traveling on, each is moving at 100 km/hr. However, if you put yourself in either of the cars, you measure the speed of the other car relative to your own position, the you will see the other car approaching you at 200 km/hr. It's important to understand that the speed must be subject to measure. You cannot infer a passing speed of 200 km/hr from some external point overlooking the passing point. From any external frame, each car is moving at 100 km/hr. Only from a frame of reference inside one of the moving cars can you arrive at a relative speed of 200 km/hr.

Velocity is direction and speed so the vehicle do not have the same velocity
What is the full speed of Ferrari's car?
it is 900km/hr
What is the distance traveled by a car that moves at a constant speed of 30 km per hr for 3 hours?
30 km/h x 3 h = 90 km
What is the average speed of A car that covers 100km in 1.5 hr?
Speed in kph = 100/1.5
Give a question about acceleration?
My car can reach a maximum speed of 150km/hr. And my car can acclerate at 5km/hr2. How long will it take for my car to reach 150km/hr from rest?
What is the speed of a car that travels 280 km in 2 hours?
The average speed is 140 km/hr
In 3 hr a car traveled 90 km what is the speed of the car?
90kph divided by 3 = 30 kph
What has more momentum a car with a speed of 20 kmh or a car moving at 100 kmh?
The magnitude of momentum is directly proportional to speed. A car moving at 100 km per hr has 5 times as much momentum as a car with equal mass moving at 20 km per hr has.
How far can a car travel in one minute at a speed of 100km per hr?
1.66km
What is the average speed of a car when it goes 30 km in 20 minutes?
90km/hr
Are engines essential for blimps?
Yes! It gives the blimp more speed and power. The speed would be up to 30 mi/hr to 75 mi/hr. That is the speed a car would go, practically! That is pretty fast for a blimp.
