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.
Momentum = (mass ) x (velocity) = (5) x (4) = 20 kg-meters/sec in the direction of the velocity.
momentum = mass times velocity momentum = .145 x 10 = 1.45 kg-m/sec
The formula is...momentum=velocity x massSo...momentum= 4m/s x 100kgmomentum= 400 kg m/s
Momentum = m V = 45 x 7.6 = 342 kg-m/sec

This can be modeled as a "collision" where momentum is conserved. Momentum equals mass times velocity (p = mv).Let's call the momentum of the student before the collision ps0 and the momentum of the skateboard before the collision pb0. Let's call the momentums after the collision ps1 and bs1.Since momentum is conserved, ps0 + pb0 = ps1 + bs1. Plugging the numbers for the momentum gives us:(45)(3) + (m)(0) = (45)(2.7) + (2.7)(m), where m is the mass of the skateboard.Simplified:135 = 2.7m + 121.513.5 = 2.7mm = 5So the mass of the skateboard is 5 kg.(Note that the units are all in kilograms, meters, and seconds they call match up in the calculations.)
Momentum is mass multiplied by velocity. The formula for momentum is: p (momentum)= m (kg ) x v (meters/second). So in this case, the mass is 9000 kg and the velocity is 3 m/s, so its momentum is 27000 kg-m/s, or N-s.
It does. Momentum=mass* velocity. Momentum is kilogram meters per second
Using the equation for conservation of momentum you can workk out the initial speed of the first truck which was 12 meters per second.
Angular momentum is defined as the cross product of a distance (from the axis of rotation) and a momentum, so you have to use units accordingly. In the SI, that would be meters x kilograms x meters / second, which you can simplify to meters squared x kilograms / second. This is equivalent to joules x seconds.
Momentum = (mass ) x (velocity) = (5) x (4) = 20 kg-meters/sec in the direction of the velocity.
The SI unit of Momentum is kilogram meters per second --> (kg*m)/s
meters and seconds
momentum = mass times velocity momentum = .145 x 10 = 1.45 kg-m/sec
kilogram-meters per second (kg.m/s)
meters,seconds,and grams
Momentum = (mass) x (speed) = (0.148) x (35) = 5.18 kilogram meters per second
