What is the momentum of a 100 kg football player who is moving at 7 miles per second?
First of all, a football player who's moving at 7 miles per second has more to worry
about than his momentum. That's 25,200 miles an hour, and if somebody doesn't
grab him, and his helmet doesn't burst into flame from the atmospheric friction,
he's going to leave the end-zone and go into low-earth orbit.
But we'll just do the math.
Momentum = (mass) x (speed)
which is easy enough, but we have to make sure that all the units are in the same
system. Right now they're not, so we have to remember to convert that "7 miles"
into meters.
Momentum = (100 kg) x (7 mi/sec) x (1,609.344 meter/mile) = 1,126,540.8 kg-m/sec
That's roughly the same momentum as a 28-ton truck moving at 100 mph.

What is the momentum of a 100 kg football player running at a speed of 4 meters per second?
The formula is...momentum=velocity x massSo...momentum= 4m/s x 100kgmomentum= 400 kg m/s
Which if either has greater momentum a 1 kg ball moving at 2 meters per second or a 2 kg ball moving at 1 meters per second?
Momentum = (mass) x (speed) (1 x 2) = (2 x 1). Their momenta are equal.
What is the momentum of a 30 kg cart moving with a speed of 10 meters per second?
The momentum is given by the formula... p=mv p=momentum m=mass v=velocity In your question your mass is 30kg and your velocity is 10m/s just do simple math and your momentum is 300kg*m/s
When an object with a momentum of 80 kg by meters per second collides with an object with a momentum of negative 100 kg times meters per second the total momentum after the collision is?
We have to assume that both bodies are initially moving along the same straight line in opposite directions, so the collision is "head on". We also have to assume that the collision is "elastic", meaning that none of the original kinetic energy is lost to heat. The final momentum is 20 Kg-m/s in the direction opposite to the original 80 kg-m/s motion.
Which has more momentum a second hand on a clock or a minute hand on a clock?
the second hand
What is the momentum of a 100 kg football player running at a speed of 4 meters per second?
The formula is...momentum=velocity x massSo...momentum= 4m/s x 100kgmomentum= 400 kg m/s
What is the mass of an object moving at 4 miles a second that has the same momentum?
4 miles per second is 6437.376m per second. Momentum is mass x velocity so mass = momentum ÷ velocity mass = momentum ÷ 6437.376 Of course, if you had given us the whole question it would have helped.
Which has more momentum a football player who weighs 120 kg running at 4 meters per second or a player who weighs 102 kg running at 5 meters per second?
The player who weighs 120 kg running at 4 meters per second has more momentum than the player who weighs 102 kg running at 5 meters per second. Momentum is calculated as mass multiplied by velocity, so the higher mass of the first player compensates for the lower velocity compared to the second player.
When moving freight car collides with an identical one that is at rest. If momentum is conserved what happens to the second car after the collision?
If momentum is conserved, the second car will start moving in the opposite direction with the same speed and momentum as the first car after the collision. This is due to the principle of conservation of momentum, which states that the total momentum of an isolated system remains constant before and after a collision.
Which if either has greater momentum a 1 kg ball moving at 2 meters per second or a 2 kg ball moving at 1 meters per second?
Momentum = (mass) x (speed) (1 x 2) = (2 x 1). Their momenta are equal.
What is the momentum of a 0.1kg mass moving with a speed of 5 meters per second?
Momentum = (mass) x (speed) = (0.1) x (5) = 0.5 kilogram-meter per second
What is the momentum of a 8 kilogram cart moving with a speed of 12 meters per second?
The momentum of an object is calculated by multiplying its mass and velocity. In this case, the momentum of the 8 kg cart moving at 12 m/s would be 96 kg*m/s.
What is the magnitude of the velocity of a 25-kilogram mass that is moving with a momentum of 100 kilogram-meters per second?
-75
