Momentum = (mass ) x (velocity) = (5) x (4) = 20 kg-meters/sec in the direction of the velocity.
100 Kg m/s
momentum = mass times velocity momentum = .145 x 10 = 1.45 kg-m/sec
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
Momentum = m V = (21) x (3 west) = 63 kg-m/sec west(Bold italics are vectors)
To convert meters per second to kilometers per hour, you multiply the speed in meters per second by 3.6. Therefore, if a car is traveling at 12 meters per second, it is traveling at 12 × 3.6 = 43.2 kilometers per hour.
100 Kg m/s
The quantity that has a unit of kilogram meter per second is momentum. Momentum is the product of an object's mass in kilograms and its velocity in meters per second, and is a measure of the motion of an object.
The mass of a object in kilograms times its velocity is its momentum.
momentum = mass times velocity momentum = .145 x 10 = 1.45 kg-m/sec
The more the mass, the more momentum you will need for an object to speed up more, or accelerate.
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
The change in velocity of the object will be 600 meters per second. This is because the velocity of the object changes direction completely after traveling half a circle, resulting in a total change of 600 meters per second.
constan velocity (is measured in meters per second)
Momentum is measured in kilogram meters per second (kg m/s). It represents the quantity of motion an object has based on its mass and velocity.
Momentum is actually measured in kilograms x meters/second, since it is the product of a mass and a speed. Momentum can be thought of as the "amount of motion", and it is a physical quantity that is conserved under all circumstances, as far as we know.
The formula for momentum is (mass)*(velocity), so the SI units would bekg m sec-1 or kg-m/sec
If you jump up, for example, with a momentum of 100 kilogram x meter / second (this can be done by jumping up at a speed of 2 meters/second, if you have a mass of 50 kilograms), then the Earth will recoil by the same amount of momentum - in the opposite direction of course. This follows directly from Conservation of Momentum.
