29.0576 meters per second.
Momentum = (mass) x (speed)But if mass is in kg, then speed should be in meters per second, otherwise we'll geta very strange unit for our momentum (kg-mile-sec-1).1 mile = 1,609.344 meters18 miles = 28,968.2 metersMomentum = (1,400) x (28,968.2) = 40,555,468.8 kg-meter per second=============================Doing a double-take on the question ... there's got to be a mistake there somewhere.The car is going " ... 18 miles per second ... ". That's roughly equivalent to the earth's meanorbital velocity around the sun, and equal to 64,800 miles per hour.18 miles per hour, or 18 meters per second, would be a lot more reasonable.But we're only here to answer the question as posted, whether it makes sense or not.
Take 200 divide by 20!
The answer is in the question. 40 m/s is how fast it is going. This means in one second, the object has traveled 40 meters. Relatively fast compared to walking or driving.
The momentum of the bike can be calculated as mass times velocity, so the momentum of the bike is 50 kg * 10 m/s = 500 kg m/s. The momentum of the rider can be calculated as mass times velocity, so the momentum of the rider is 30 kg * 10 m/s = 300 kg m/s.

The elephant walking at 3 meters per second east has more momentum because momentum is defined as mass multiplied by velocity, and the elephant has much more mass than the mouse. The higher velocity of the elephant further contributes to its greater momentum compared to the mouse.
33.33 meters per second.
6m/1.4s = 4.29M/S
69 meters per second
29.0576 meters per second.
900 meters/30 seconds = 30 meters/second
At 40 centimeters per second, you are traveling 24 meters per minute.
