It appears from the question that the balls stick together after the collision.
Linear momentum is conserved. The linear momentum is the total of the product of mass and velocity for each of the balls.
The linear momentum before is (1.4 x 3) + (0 x 2) = 4.2 kgms-1.
The linear momentum after is v x (3 + 2) = 4.2kgms-1, since we know it is conserved.
Hence, v = 4.2 / 5 = 0.84ms-1, in the same direction of travel as the 3kg ball was originally moving.
The idea is to use conservation of momentum. Calculate the total momentum before the collission, add it up, then calculate the combined velocity after the collision, based on the momentum.
Total momentum before the collision = total momentum after the collision As a reminder, momentum is the product of velocity and mass.
inelastic collision The formulas for the velocities after a one-dimensional collision are: where V1f is the final velocity of the first object after impact V2f is the final velocity of the second object after impact V1 is the initial velocity of the first object before impact V2 is the initial velocity of the second object before impact M1 is the mass of the first object M2 is the mass of the second object CR is the coefficient of restitution; if it is 1 we have an elastic collision; if it is 0 we have a perfectly inelastic collision
The combined VELOCITY of two cars that crash will be somewhere between that of the individual cars. In this case, the combined speed will be less than the speed of the car that was moving before the crash.If you know the velocities and the masses, the exact speeds can be calculated using conservation of momentum.
In a uniform circular motion,the magnitude of velocity remains constant,that is speed is constant,however due to change in direction in circular path constantly the motion is accelerated due to change in velocity.
The smaller vehicle will encounter the larger velocity change.

We know that momentum is conserved, so we'd have no trouble answering that question if you had just told us what their velocities were before the collision.
A collision where the velocity remains the same but there is impact still.
The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".
Total momentum before the collision = total momentum after the collision As a reminder, momentum is the product of velocity and mass.
To calculate the velocity after a perfectly elastic collision, you need to apply the principle of conservation of momentum and kinetic energy. First, find the initial momentum of the system before the collision by adding the momenta of the objects involved. Then, find the final momentum after the collision by equating it to the initial momentum. Next, solve for the final velocities of the objects by dividing the final momentum by their respective masses. Finally, make sure to check if the kinetic energy is conserved by comparing the initial and final kinetic energy values.

Nah, brah. Momentum and kinetic energy are conserved, but velocity is not. Correct me if I am wrong but from how I interpret this, any collision cause the colliding bodies to change their direction. Thus velocity, which is a vector quantitiy containing direction, is by definition changed in an elastic collision. I guess speed, which is the magnitude of the velocity, can be considered as being conserved?
If initial velocity is zero, the collision seems unlikely.
ask any witnesses of the collision if they've seen velocity. it might help to bring a picture of it to help the people recognize who you're looking for. you could also ask the police when they show to to help search for it.
