First, know that p = mv, where p = momentum, m = mass, and v = velocity.
Let Car A be the car with twice the mass, and Car B be the car with twice the velocity.
The momentum of Car A has to be in relation to the momentum of Car B, so:
Car A:
p = mv write the equation
p = 2mv write the equation in relation to Car A
p = 2(mv) realize that the new equation is twice the old
2p
Car B:
p = mv
p = m2v
p = 2(mv)
2p
So the cars have the same momentum!

How fast does electricity travel in one second?
Depends on the medium through which it is traveling.
What is the velocity if you travel 882 ft in 5 seconds?
Assuming that you travel 882 feet in a straight line, the average velocity is 882.5 = 176.4 feet per second.
How fast are you travelling if you travel 10m in 2 seconds?
You are traveling 10 min 2 seconds. Therefore, you are traveling 5 m per second. (or 300 m per minute or 18,000 m per hour).
A ferris wheel with radius of 20 meters is rotating at a rate of 1 revolution every 3 min how fast is a rider rising when his seat is 24 m above ground level?
Here is an outline of the solution: Find the velocity of a point on the rim by multiplying the radius times the angular velocity in radians per second (converted from 1 rev per 3 min.). The direction of the rim velocity is tangent to the rim. You have to find the vertical component of this velocity using trig. You find the necessary angle to do this by drawing a radial line to the point on the rim that is 24 m above ground level. There are several parts to this problem, so good luck.
What is x to the second power plus x to the second power?
x² + x² = 2x²
The momentum of a 1500kg car traveling at a velocity of 10miles per second is?
150n
What is the momentum of a 5 kg object traveling at 4 meters a second?
Momentum = (mass ) x (velocity) = (5) x (4) = 20 kg-meters/sec in the direction of the velocity.
What is the momentum of a 0.145 kg softball traveling at 10 meters per second?
momentum = mass times velocity momentum = .145 x 10 = 1.45 kg-m/sec
What is the momentum of two cars that are 0.04 kg with tape on the bumpers if one is stopped on the track and the other is traveling at a velocity of 4 miles per second?
te momentum would be 9o
Why does momentum have no designated SI unit name?
It does. Momentum=mass* velocity. Momentum is kilogram meters per second
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.
What is the momentum of a 22.6 Newton bowling ball with a velocity of 6.32 miles per second?
momentum is velocity x mass. Its mass in kilograms is 22.6N/9.8 m/s/s= 2.306kg The velocity is 6.32 miles per second which is 10112 meters per second. The momentum is 2.306 x 10112 which=23318.272 kg meters per second.
What is the momentum of a truck with a mass of 4500 kg traveling at 25 m s?
112500 kg m/s
How is an object's momentum determined?
The momentum of a body is detemined by its mass and velocity. To find the non-directional momentum, multiply the mass in kilograms times the speed in meters per second to yield the momentum in newton-seconds (N-s).
What is the formula of total momentum?
_______________________________________________________ P = m x v P = momentum m= mass v = velocity _______________________________________________________ P t = P 1 x P 2 Total momentum = Momentum 1 X Momentum 2 Total momentum = ( mass x velocity of the first object ) x ( mass x velocity of the second object )
What is momentum and state its SI unit?
Momentum is mass * velocity. Its units, in the SI system are kilogram metre per second
What is the relationship between momentum and mass?
The more the mass, the more momentum you will need for an object to speed up more, or accelerate.
