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.

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 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 momentum of a 45 kilogram bike going 7.6 meters per second?
Momentum = m V = 45 x 7.6 = 342 kg-m/sec
What are the units you use for measuring a moment?
If you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / secondsIf you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / secondsIf you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / secondsIf you mean a brief moment of time: seconds.If you mean momentum: this is mass x velocity, so the units are kg x meters / seconds
A 8 Kg blob of clay moving horizontally at 2 meter per second hits a 4 Kg blob of clay at rest. What is the speed of the two blobs stuck together immediately after the collision?
The law of conservation of momentum states that the total momentum before the collision is equal to the total momentum after the collision. Using this principle, we can determine the velocity after the collision to be ( \frac{8 \times 2 + 4 \times 0}{8 + 4} = \frac{16}{12} = 1.33 ) meters per second.
Which is A student weighing 45kg runs down a slope and suddenly jumps with a speed of 3 m s onto a stationary skateboard The student and the skateboard move with a velocity of 2.7 m s What is the mass?
The mass of the skateboard is 11.25 kg. This can be calculated using the principle of conservation of momentum, where the momentum of the student before jumping is equal to the momentum of the student and skateboard after jumping.
Spaceship 1 and spaceship 2 have equal masses of 300 kg spaceship 1 has a speed of 0 ms and spaceship 2 has a speed of 6 ms If they collide and stick together what is the combined momentum?
The momentum of an object is given by the product of its mass and velocity. Therefore, the momentum of spaceship 1 before the collision is 0 kgm/s and the momentum of spaceship 2 before the collision is 1800 kgm/s. When they collide and stick together, their momenta are added, resulting in a combined momentum of 1800 kg*m/s.
A 3000kg truck runs into the rear of a 1000 kg car that was stationary the truck and car are locked together after the collision and move together at nine meters per second What was the trucks speed?
Using the equation for conservation of momentum you can workk out the initial speed of the first truck which was 12 meters per second.
What is unit of angular momentum?
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.
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 unit for momentum?
The unit for momentum is kilogram meters per second (kg m/s).
The momentum of a bowling ball decreases by 0.5 kg meters per second when it hits some pins How much momentum did the pins gain Explain?
The pins gained the same amount of momentum that the bowling ball lost, according to the law of conservation of momentum. So, the pins gained 0.5 kg meters per second of momentum in the opposite direction to the bowling ball's initial momentum.
What are the units for momentum?
The units for momentum are kilogram meters per second (kg m/s). Momentum is calculated by multiplying an object's mass (in kilograms) by its velocity (in meters per second).
A boy weighs 40 kilograms He runs at a velocity of 4 meters per second what is his momentum?
The momentum of the boy is calculated by multiplying his mass by his velocity. Therefore, the momentum of the boy is 160 kilogram meters per second (40 kg x 4 m/s).
What is the unit of measuement for momentum?
The unit of measurement for momentum is kg*m/s (kilogram meters per second).
A 0.068-kilogram ball with a velocity of 22.1 meters per second strikes a wall. The wall stops the ball in 0.36 second. What is the average magnitude of the force applied to the ball by the wall?
To find the average force, we need to use the equation: average force = change in momentum / time. First, calculate the initial momentum of the ball: momentum = mass * velocity. Then, calculate the change in momentum by subtracting the initial momentum from 0 (since the ball stops). Finally, divide the change in momentum by the time taken for the collision to find the average force applied by the wall.
