100 Kg m/s

Momentum = (mass ) x (velocity) = (5) x (4) = 20 kg-meters/sec in the direction of the velocity.

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.

Depends how fast you are traveling. On a highway,about 15- 20 min.

-- "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.

Momentum = M V = 100 kg-m/s

Momentum = M V = 100 kg-m/s

Momentum = Î¡ = mâ€¢v, m is mass in kg, and v is velocity in m/s. Both the semi and the linebacker are traveling at the same velocity. However, the mass of the semi is hundreds of times the mass of the linebacker. Therefore, the semi will have a much greater momentum than the linebacker.

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.

Momentum = (mass ) x (velocity) = (5) x (4) = 20 kg-meters/sec in the direction of the velocity.

Momentum = speed multiplied to mass. M'm = 5 ms^-1 X 20 kg . M'm = 100 kg m s^-1

Momentum = Mass * Velocity, so all you have to do is multiply those numbers together. 20 kg * 5 m/s = 100 kg*m/s.

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.

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.

Use the momentum equation! ∑M * V = (20 + 1000)(10) = 10,200
