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.

Two gliders having the same mass and speeds move toward each other on an air track and stick together After the collision the velocity of the gliders is?
Zero.
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
What happens to the momentum of two objects which collide and stick together?
In a collision, a force acts upon an object for a given amount of time to change the object's velocity. The product of force and time is known as impulse. The product of mass and velocity change is known as momentum change. In a collision the impulse encountered by an object is equal to the momentum change it experiences.Impulse = Momentum Change. What happens to the momentum when two objects collide? Nothing! unless you have friction around. Momentum#1 + Momentum#2 before collision = sum of momentums after collision (that's a vector sum).
What does acceleration mean as a science term?
It's the change in velocity, the rate of change (derivative) which is instantaneous velocity. Acceleration can be positive or negative, meaning increased or decreased velocity respectively.
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.
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".
Two gliders having the same mass and speeds move toward each other on an air track and stick together After the collision the velocity of the gliders is?
Zero.
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?
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.

What happens when there is a head on collision of two bodies moving at uniform velocity?
they both crash

It's the change in velocity, the rate of change (derivative) which is instantaneous velocity. Acceleration can be positive or negative, meaning increased or decreased velocity respectively.
