momentum change = 670.56 kilogram-meter/second
You need to know the mass. The equation for momentum (p) is p = mv, where m is the mass in kg and v is the velocity in m/s.
Since momentum is mass x velocity, the vehicle with the greater mass would have more momentum in this case.
The original answer is misleading 15MPH is world class. Sprinting up to 100 yards - record is ~23 MPH - average ~14 Running up to a mile /1600 meters record is ~16MPH - average ~10MPH Marathon distance record ~26 Mile/42 Km is ~13MPH/21KmPH reasonable 9MPH 14KmPH (NY marathon qualification time) For figuring out how fast you can get between two points these are probably better values as they assume you can actually not spend too much time recovering. The Average walking speed is 3-4 MPH 5-6 KmPH or about 100 yards/meters per minute Running speed sustained is about twice that 8 MPH, 12 KmPH or 200 yards/meters per minute.
It can change, but it's always equal to (mass of the ball) times (speed of the ball).
The only thing that matters is the RELATIVE Velocity between the two Objects, not whether they are BOTH moving or not. If one is standing still and the other going 100 MPH, the result is the same as if both were going 50 MPH.
momentum
An average of 15 mph.
a ant running the equation for momentum is p=mv so plug in the numbers an ant weighing . 1 pounds moving at 1mph is p=.1*1 is .1pound/mph a ship at rest has no momentum because velocity = 0
The man is approximately running at 9.3205679 mph.
He is running at an average speed of 21.31 mph.
The person on the conveyor belt is moving at 120 mph relative to the ground. This is because the person is running at 20 mph relative to the conveyor belt, and the conveyor belt is moving at 100 mph relative to the ground. Therefore, the person's total speed is the speed of the conveyor belt (100 mph) plus the speed of the person relative to the conveyor belt (20 mph), giving a total speed of 120 mph.
An average of 17.2 mph
Running 100 meters in 12.5 seconds is equivalent to running at a speed of 22.4 miles per hour.
You need to know the mass. The equation for momentum (p) is p = mv, where m is the mass in kg and v is the velocity in m/s.
Usain Bolt was clocked running 23 mph during the 2008 Beijing Olympics 100 meter dash
100 kph = 62.1 mph
Momentum is calculated by multiplying mass by velocity. If both vehicles have the same mass, the one traveling at 60 MPH will indeed have three times the momentum of the one going 20 MPH, since 60 is three times 20. Therefore, the statement is correct, assuming both vehicles have equal mass.
