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.

Two balls of masses 500gram and 200 gram are moving at valocities 4m s and 8m s respectively on collision they stick together find the velocity af the system after collision?

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.


Which expression represents the speed v of the masses after the collision?

Total momentum before the collision = total momentum after the collision As a reminder, momentum is the product of velocity and mass.


Which type of collision occurs when a baseball bat hits a baseball?

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


How does the speed of the combined cars compare to the speed of the car before the collision when a parked car is hit by a moving car and the two cars stick together?

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.


Which physical quantity remains constant in an elastic collision?

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.

If m1 is 2kg and sticks to m2 which is 1kg after the collision what is the velocity of the combined mass immediately after impact?

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.


What is glancing collision?

A collision where the velocity remains the same but there is impact still.


What happens to the total momentum of two objects in a system before and after interactions?

The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".


Which expression represents the speed v of the masses after the collision?

Total momentum before the collision = total momentum after the collision As a reminder, momentum is the product of velocity and mass.


How do you calculate velocity after perfectly collision?

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.

Is velocity conserved in elastic conditions?

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?


When two coins of mass 2 kg and 4 kg respectively collide what will be the change in velocity if initial velocity is 0?

If initial velocity is zero, the collision seems unlikely.


How do you find velocity after a collision?

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.
