Which car has more momentum a car with the speed of 20 km per h or a car moving at 100 km per h?

Momentum = mass * velocity. If both cars have the same mass, then the faster one will have more momentum. Probably the slow car doesn't weigh 5 times as much as the fast one, so the fast one most likely has more momentum.

What is the momentum of a 100 kg football player running at a speed of 4 meters per second?
The formula is...momentum=velocity x massSo...momentum= 4m/s x 100kgmomentum= 400 kg m/s
What is the momentum of a 100 kg football player who is moving at 7 miles per second?
First of all, a football player who's moving at 7 miles per second has more to worryabout than his momentum. That's 25,200 miles an hour, and if somebody doesn'tgrab him, and his helmet doesn't burst into flame from the atmospheric friction,he's going to leave the end-zone and go into low-earth orbit.But we'll just do the math.Momentum = (mass) x (speed)which is easy enough, but we have to make sure that all the units are in the samesystem. Right now they're not, so we have to remember to convert that "7 miles"into meters.Momentum = (100 kg) x (7 mi/sec) x (1,609.344 meter/mile) = 1,126,540.8 kg-m/secThat's roughly the same momentum as a 28-ton truck moving at 100 mph.
A rocket ship is moving through space at 1000meters per second It accelerates in the same direction at 4meters per second What is its speed after 100 seconds?
The speed after 100 seconds is: speed =1000m/s + 4m/s^2x100s= 1000m/s + 400m/s=1400 m/s.
When an object with a momentum of 80 kg by meters per second collides with an object with a momentum of negative 100 kg times meters per second the total momentum after the collision is?
We have to assume that both bodies are initially moving along the same straight line in opposite directions, so the collision is "head on". We also have to assume that the collision is "elastic", meaning that none of the original kinetic energy is lost to heat. The final momentum is 20 Kg-m/s in the direction opposite to the original 80 kg-m/s motion.
What is the acceleration of a car moving along a straight line path that increases its speed from zero to 100 kilometers per hour in ten seconds?
If you want to have that in meters per second square, convert the speed to meters per second (divide by 3.6 in this case). Then, divide the speed by the time.
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.
Would an oil ship moving at 10kmh have more or less momentum than a car moving at a speed of 100 kmh?
momentum is mass x velocity. Even though the car is moving ten times faster, the ship mass is hundreds of times more, so the ship has more momentum
What is the momentum of an object that is moving in a straight line at a speed of 10 m s and has a mass of 10 kilograms?
100 Kg-m/s
When could a small object have the same momentum as a large object?
Yes. Momentum is based on mass and velocity, not physical size. 1 kg of styrofoam moving at 100 m/s has the same momentum as 1 kg of gold moving at 100 m/s, but the piece of styrofoam will be over 1000 times the size. Additionally, since the formula for momentum is mass times velocity, a 10 kg piece of gold moving at 10 m/s has the same momentum as a 1 kg piece of gold moving at 100 m/s. They both have a momentum of 100 kg-m/s.
What is a example of a momentum of zero?
An object at rest. Actually that's the only possible example for a single object. For two objects, you can have objects moving in opposite directions; for example, one may have a momentum of +100 units, and the other, a momentum of -100 units.
Why 3000 kg mass moving at .2 m s has a big momentum?
Momentum in classical mechanics is defined as mass times velocity. The magnitude of the momentum of an object with mass 3000kg and speed 0.2 m/s has a momentum of 600 mkg/s. A human walking at the same speed of 0.2 m/s weighing, let's say, 100 kg has a momentum of 20 mkg/s which is 30 times smaller.
Which has a greater momentum a heavy truck at rest or a moving automobile?
The momentum of any object depends on its mass and its speed. If a car and a bike are both moving at the same speed, then the car has more momentum because it has more mass than the bike. If the car and the bike are moving at different speeds, then we need to know the speeds of each, in order to make any determination about their respective momenta.
What is the magnitude of the velocity of a 25-kilogram mass that is moving with a momentum of 100 kilogram-meters per second?
-75

When a car is moving at a steady speed of 100 kilometres per hour why does it use more petrol to keep it going than if it was moving at 60 kilometres per hour?
I believe at higher speeds there will be more air resistance.
What is the speed of a train that is moving 500 km in 5 hrs?
100 kph
