Momentum = mass*velocity in the direction of the motion.
Now 30 miles per hour = 44 feet per second so the momentum is
200*44 = 8800 foot pounds per second in the direction of the car's motion.
What is the momentum of a 2000-pound car traveling at 30 miles per hour? Give the answer in metric units (change pounds to kilograms; miles per hour to meters per second).Choose the best answer from the options below:A10,900B12,120C9,000D13,140E15,000
2000 pounds = 907.2 kg 30 mph = 13.41 m/s momentum = velocity * mass momentum = 13.41 m/s * 907.2 kg momentum = 12166 kg*m/s
The momentum is the mass times the velocity, or 6000 pounds*mi/hr. Normally, you would use SI units, which means you would convert 200 lb to newtons, and 30 mi/hr to meters per second.

no force, it has momentum
depends on how fast you're going. at 30 MPH it will take one hour. At 60 MPH half an hour.
2000 pounds = 907.2 kg 30 mph = 13.41 m/s momentum = velocity * mass momentum = 13.41 m/s * 907.2 kg momentum = 12166 kg*m/s
49 miles = 78.9 kilometres so 49 miles per hour = 78.9 km per hour.
That would depend on the mass of the marble.
INITIAL MOMENTUM = FINAL MOMENTUM ∑M1V1 + M2V2 +… + MnVn = ∑ M1V1 + M1V1 +… + MnVn + or momentum=mass x acceleration unit for momentum=kg x m/sec its confusing...
35 mph = 0.0156464 kilometers per second.
The momentum is the mass times the velocity, or 6000 pounds*mi/hr. Normally, you would use SI units, which means you would convert 200 lb to newtons, and 30 mi/hr to meters per second.

work out
The momentum of an object is the product of both the mass and velocity of the object. A train moving at ten miles per hour will have more momentum than a ball moving at ten miles per hour, because the train is much heavier and larger.
