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.
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.
INITIAL MOMENTUM = FINAL MOMENTUM ∑M1V1 + M2V2 +… + MnVn = ∑ M1V1 + M1V1 +… + MnVn + or momentum=mass x acceleration unit for momentum=kg x m/sec its confusing...
-- foot-pound -- watt-second -- watt-hour -- kilowatt-hour -- horsepower-hour -- inch-pound SI unit: Joule
The large truck moving at 30 miles per hour will have more momentum because momentum is directly proportional to an object's mass and velocity. Since the large truck has more mass than the small truck, it will have more momentum at the same speed.
