How do you find magnitude of initial momentum?
INITIAL MOMENTUM = FINAL MOMENTUM ∑M1V1 + M2V2 +… + MnVn = ∑ M1V1 + M1V1 +… + MnVn + or momentum=mass x acceleration unit for momentum=kg x m/sec its confusing...
What is the magnitude of the final momentum of the ball?
QUESTION: A volleyball of mass 0.25 kg traveling with velocity ~vi = (0.65 m/s)ˆı + (−15.6 m/s) ˆ +(−1.3 m/s) ˆk is set up perfectly for a spike. A player spikes the ball with force F~ spike = (405 N)ˆı + (−1089 N) ˆ +(−464 N) ˆk over an interval of ∆t = 0.077 s. What is the magnitude of the ball's final momentum? Answer in units of kg · m/s. What angle does the final momentum make with the initial momentum? Answer between −180◦ and +180◦ . Answer in units of ◦ .
How is the change in momentum calculated?
IN general change is defined as the difference of initial from the final. So change = Final - Initial. Hence change in momentum = Final momentum - initial momentum
As momentum of an object decreases what happens to the veocity?
An object that decreases its speed also decreases the magnitude of its velocity and decreases the magnitude of its momentum. Momentum is mass time velocity. Less velocity, less momentum. Technically, velocity is a vector and therefor momentum is a vector. One can speak of smaller or larger magnitudes of a vector, but not smaller and larger vectors because vectors have magnitude and direction. Speed is the magnitude of velocity.
What Does it Men To Momentum is Conserved?
When momentum is conserved, the initial momentum is equal to the final momentum.
When two bodies having same momentum collide what will be the result?
There are two possible results. However, they cannot move in the same direction after the collision.Total initial momentum = p - p = 0where p represent the momentum of each object.From the principle of conservation of momentum;Total initial momentum = Total final momentumThus, Total final momentum = 0There are only two possibilities for this:1. Kinetic energy is conserved. (the collision is perfectly elastic)In this case, they would move away from each other with the same magnitude of initial momentum.2. Kinetic energy is not conserved. (the collision is inelastic)In this case, they would either remain at rest or they will move away from each other with a smaller magnitude of initial momentum each had.Note that if both bodies had moved in the same direction, there would be a net momentum in this direction and momentum would not have been conserved. (Momentum is ALWAYS conserved provided there is no external force acting on the system)
Which is greater the momentum of a bullet fired from a rifle or the momentum of the rifle's recoil?
Both are equal in magnitude but in opposite direction
An object of mass 3.0 kg is projected into the air at an angle of 55 degrees It hits the ground 3.4s later What is the change in momentum while it is in the air?
The initial momentum is 61.0 Newton-seconds at an elevation of 55 degrees to the horizontal while the final momentum has the same magnitude but is at a depression of 55 degrees. This represents a change in momentum of 70 Newton-seconds.
A spaceship has a momentum of 20 000 kg-ms to the left and a mass of 500 kg What is the magnitude of its velocity?
momentum = mass x velocity, so velocity is momentum/mass. If the question asks for the magnitude then it's probably the absolute magnitude rather than a directional value (which would be negative as the space ship is heading to the left.
When objects collide the totol inital momentum equals the total final momentum is what?
law of conservation of momentum
What is the momentum conservation's principle?
After a collision,The initial momentum of a system is equal to final momentum. m1V1=m2V2
Momentum Magnitude?
A measurement system derived from the amount of displacement (energy) of the earthquake.
