The momentum of an object is calculated by multiplying its mass by its velocity. In this case, the momentum of the 800kg car traveling at 20 m/s would be 16,000 kg m/s. Momentum is a vector quantity, meaning it has both magnitude and direction, which in this case would be in the direction of the car's motion.
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.
The momentum of an object is calculated by multiplying its mass by its velocity. In this case, the momentum of the 20 kg object traveling at 5 m/s would be 20 kg * 5 m/s = 100 kg*m/s.
The momentum of Car A is mv = 20 kg m/s, while the momentum of Car B is mv = 40 kg m/s. The difference in momentum between the two cars is 20 kg m/s, with Car B having the greater momentum due to its higher mass.
The bowling ball traveling at 20 kph has greater momentum than the one traveling at 10 kph, assuming both have the same mass. Momentum is calculated using the formula ( p = mv ), where ( p ) is momentum, ( m ) is mass, and ( v ) is velocity. Since the second ball has a higher velocity, its momentum will be greater, making it more impactful in motion.
Momentum = M V = 100 kg-m/s
Momentum is calculated as the product of an object's mass and its velocity. Therefore, a bowling ball traveling at 20 kph has greater momentum than one traveling at 10 kph, assuming both balls have the same mass. The increase in speed directly increases the momentum, making the 20 kph ball more impactful than the 10 kph ball.
Momentum = Ρ = m•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.
Momentum = speed multiplied to mass. M'm = 5 ms^-1 X 20 kg . M'm = 100 kg m s^-1
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 = M V = 100 kg-m/s
100 Kg m/s
Momentum = (mass ) x (velocity) = (5) x (4) = 20 kg-meters/sec in the direction of the velocity.
Momentum = Mass * Velocity, so all you have to do is multiply those numbers together. 20 kg * 5 m/s = 100 kg*m/s.
