Which is A child weighing 20 kg sitting inside a car of mass 1000 kg moves with a velocity of 10 m s What is the momentum of the child?

-- "20 kg" is the child's mass, not her weight.
-- The car's mass doesn't matter.
The child's momentum is (M V) = (20) (10) = 200 kilogram-meters per second.

How do slip off slopes form?
When alluvium is deposited on the inside of meanders. It is deposited because velocity is slower there
Can You calculate the velocity of a fart?
Generally wind speed is measured using a cup anemometer (wind speed measuring device). The velocity of a flatulation will decrease as it leaves the anus, so to properly measure the velocity the measurement would have to be done before the exit. Theoretically you could measure the velocity of the gases by placing a miniature cup anemometer with walls inside the rectal tract close to the anus to give an approximate wind speed (velocity) of the gases.
What is a synonym for inside?
the answer for inside is interior
Does area mean outside or inside?
inside
Should a question mark be inside bracket or outside?
Inside if the sentence inside the brackets is a question.
Which is A child weighing 20 kg sitting inside a car of mass 1000 kg moves with a velocity of 10 m s What is the total momentum of the child and the car together?
Use the momentum equation! ∑M * V = (20 + 1000)(10) = 10,200
How do the mass and velocity of a moving object affects its momentum?
As the velocity decreases, the momentum increases. Mass is the matter inside of something and momentum is how hard it is to stop something. Therefore momentum needs mass to function because without mass there would be no momentum. So think of the sentence above like this: velocity ( a measure of momentum) decreases, the momentum (including mass inside an object) goes up therefore making the mass increase while the velocity decreases.
When comparing the momentum of a bus filled with fuel and people and a small car both travelling at the same speed which one has more momentum?
The bus filled with fuel and people would have more momentum than the small car, as momentum is mass multiplied by velocity. The bus has more mass due to the fuel and people inside, even if they are both traveling at the same speed.
How can a butterfly have the same momentum as a freight train if they are both in motion?
The butterfly can have the same momentum as the freight train if it has a much higher velocity to compensate for its smaller mass. Momentum is a product of an object's mass and velocity, so as long as the butterfly is moving significantly faster than the train, it can have the same momentum.
What is does momentum have to do with bottle rockets?
In the context of bottle rockets, momentum plays a critical role in propelling the rocket forward. When the compressed air inside the bottle is released, it exerts a force on the rocket in one direction, causing it to move in the opposite direction due to conservation of momentum. The momentum of the expelled air pushes the rocket upward with enough force to overcome gravity and create the motion.
What causes the transfer of momentum to the inside particles?
The transfer of momentum to inside particles is caused by collisions between the particles. When an external force is applied to a system, it causes the particles to collide with one another, transferring momentum in the process. This transfer of momentum results in the acceleration of the particles and the overall motion of the system.
Define the conservation of momentum?
the principle that the total linear momentum in a closed system is constant and is not affected by processes occurring inside the system.
Can sitting inside a running car with windows closed harm you?
sitting in a running car with windows closed is any fumes released inside of car.
Is The reason a penny thrown straight up inside a bus will come back to your hand is because you the bus the air inside the bus and the penny are all moving at the same velocity?
No, the reason a penny thrown straight up inside a bus will come back to your hand is due to the principle of inertia. When the bus moves forward, everything inside it, including the air and the penny, moves forward at the same velocity due to inertia. Thus, when the penny is thrown up, it still retains some of that forward momentum, allowing it to return to the hand as the bus moves forward.
A molecule inside a cell consists of 3500 covalently linked atoms weighing about 105000 daltons?
A macromolecule
Which side of the stream is shallower the inside curve or outside?
Since the outside curve has a higher velocity, it has more erosion meaning the inside curve has a slower velocity more deposition causing it to be shallower. The outside curve is deep.
What two forces compress a spring inside a weighing scale when you weigh yourself?
The two forces that compress a spring inside a weighing scale are the force of gravity acting on the person standing on the scale and the reaction force exerted by the spring in the scale to counteract the force of gravity. This compression of the spring is used to measure the weight of the person.
