How do you find magnitude of final momentum?
Use this formula:Final momentum = (initial momentum) + (change in momentum)
If A 0.50 kg ball with a speed of 4.0 strikees a stationary 1.0 kg target if momentum is conserved what is the total momentum of the ball and target after te collision?
When the 0.500kg ball collides with the stationary ball, momentum is conserved. Meaning, initial momentum = final momentum. Momentum of an object is = mass(m) x velocity (v). If two objects are in the system, then you have to add up both initial momentums and set them equal to the final momentums... So... m x v(initial, first object) + m x v(initial, second object) = final momentum. (0.500kg)(4.0m/s) + (1.0kg)(0m/s) = final momentum. So the final momentum equals 2.0kgm/s... D. 2.0 kgm/s
When a ball is thrown up the magnitude of its momentum decreases and then increases.Does this violate the conservation of momentum principle?
No, because the conservation momentum principle is only valid when none force is applied. And here you have the gravity force.
In order to increase the final momentum of a golf ball you could?
Hit it harder with a club.
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...
Tennis ball have momentum?
Momentum is calculated by taking the product of mass times velocity. Thus, a moving tennis ball would have a nonzero momentum. However, since a tennis ball has a relatively small mass, it would need to have a high velocity in order to have a large value for its momentum. Since velocity is a vector (having both a magnitude and a direction), momentum is also a vector. When a tennis player hits a tennis ball with his racket, he imparts a force onto the tennis ball, which changes the direction of its momentum to return it over the net. (The value for this change in momentum is called impulse, which is equal to the product of the force applied and the time for which it is applied.)
How can a bowling ball and a volleyball have the same momentum?
Linear momentum, p=mv, is proportional to mass and velocity. Since the bowling ball far outweighs the volleyball, the difference in velocity would have to be determined in order for them to possess the same amount of momentum. If the volleyball is traveling at a high enough speed (orders of magnitude higher), they can both have the same momentum. Either that or fill the volleyball with concrete.
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.
A ball with a mass M is falling on to the ground with some velocity V1 and raising with velocity V2 find the impulse?
Impulse = |change in momentum| Initial momentum = MV1 down Final momentum = MV2 up Missing momentum = impulse = M ( V1 - V2 )
A baseball flies through an open window and collides with a vase The momentum of the ball and vase after the collision is?
A baseball flies through an open window and collides with a vase. The momentum of the ball and vase after the collision is the same as the momentum of the ball alone before the collision.
