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.

How do you find speed if you know the velocity?
Velocity is speed and direction
When calculating acceleration to find the change in velocity do you subtract the initial velocity from the final velocity?
Yes.
How do you find a final velocity without distance but given time?
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
How do you find final Velocity of an object?
The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).
What is the formula to find time in seconds from velocity and distance?
Distance divided by velocity = time
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.
What is glancing collision?
A collision where the velocity remains the same but there is impact still.
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
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.
What is the equation for an elastic collision?
Well technically you can use the same equation for elastic collisons to find the velocity. (first mass*its velocity)+(secind mass*its velocity)=(first mass*new Velocity)+(second mass*new velocity) OR... if its inelastic the seccond half of the equation can look like: (first mass+second mass)*Final Velocity and the formula for kinetic energy is: .5mv^2
What happens when there is a head on collision of two bodies moving at uniform velocity?
they both crash
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".
A construction truck collides with the back of a subcompact car Which one has the larger change of velocity during the collision?
The smaller vehicle will encounter the larger velocity change.
How do you find the final velocity of two objects coupled?
The case you're describing is called an inelastic collision. Two objects collide, stick to each other and continue their motion as one body. Due to momentum conservation principle, sum of two bodies momenta before collision has to be equal to momentum of the one body after collision. pbefore = pfirst + psecond = m1v1 + m2v2 pafter = (m1 + m2)vcommon Since pbefore = pafter, (m1 + m2)vcommon = m1v1 + m2v2 We can get vcommon from that: vcommon = (m1v1 + m2v2) / (m1 + m2) [vi are velocities of bodies before collision and vcommon is a velocity after collision]
