# When a billiard ball moving with a speed of 5 Metre per second collides with an identical ball?

## When a billiard ball moving with a speed of 5 Metre per second collides with an identical ball?

It is a case of elastic collision. As masses of two balls are equal and 2nd ball is at rest before collision, hence after the collision the speeds are just exchanged, ie, 1st ball will now come to rest while the second ball will move forward with the same speed as that of the first ie, 5ms−1.

## Is the total linear momentum conserved during the short time of an elastic collision of two balls?

Yes, the total linear momentum conserved during the short time of an elastic collision of two balls because total momentum conserves as per the law of conservation of momentum.

## What is the change in the total kinetic energy of the two balls as a result of the collision?

If two balls of same mass with speed v and −v undergo an elastic collision, the kinetic energy will be the same after the collision as before.

## Is linear momentum conserved during collision?

Linear momentum is the product of the mass and velocity of an object, it is conserved in elastic and inelastic collisions.

## What is the formula for the velocity of two objects after a collision?

From the conservation of momentum, the formula during a collision is given by: m1v1 + m2v2 = m1v’1 + m2v’2. If the collision is perfectly inelastic, the final velocity of the system is determined using v’ = (m1v1 + m2v2)/m1 + m2.

## What is the velocity of the 3 kg ball after the collision?

The velocity of the 3 kg ball is 4 m/s after the collision.

## Is linear momentum conserved when two objects collide and stick together is kinetic energy conserved?

The two objects come to rest after sticking together, conserving momentum but not kinetic energy after they collide. Some of the energy of motion gets converted to thermal energy, or heat. Figure 8.7 A one-dimensional inelastic collision between two objects. Momentum is conserved, but kinetic energy is not conserved.

## How to find momentum?

Step 1: List the mass and velocity of the object. Step 2: Convert any values into SI units (kg, m, s). Step 3: Multiply the mass and velocity of the object together to get the momentum of the object.

## Is linear momentum conserved when two objects collide and stick together?

In collisions between two objects momentum is conserved. Since the initial momentum is not zero, the final momentum is not zero. Both objects cannot be at rest. It is possible for one of the objects to be at rest after the collision.

## What is the formula for total momentum?

The total momentum (ptot) of a system is equal to the sum of the momenta of all objects within that system. p t o t = p 1 + p 2 + p 3 + . . . Furthermore, the momentum of each of the individual objects in the system is equal to the mass (m) of that object multiplied by its velocity (v).

## What’s the formula for kinetic energy?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

## What is the formula for momentum collision?

Before the collision, one car had velocity v and the other zero, so the centre of mass of the system was also v/2 before the collision. The total momentum is the total mass times the velocity of the centre of mass, so the total momentum, before and after, is (2m)(v/2) = mv.

## When a billiard ball collides in an elastic head-on collision with a second stationary identical ball after the collision?

1 Expert Answer Since the billiard balls are of equal mass, when this situation occurs in an elastic collision all of the momentum from the first ball will be transferred to the second ball giving a final velocity of the second ball of 12 m/s.

## When a billiard ball collides with another billiard ball at angle is momentum still conserved?

Since they have the same mass, Ball 1 will decelerate at the same rate Ball 2 accelerates. However, after a certain amount of time, both balls will have the same amount of momentum in the same direction.

## What type of collision is it when two billiard balls collide on a billiard table?

When two billiards balls collide, the bump is almost elastic. An elastic collision is one in which the kinetic energy of the system is conserved before and after the collision.

## What happens to the momentum of a pool ball when it collides with another pool ball?

No matter what type of collision you have, momentum will be conserved. This means that the total momentum of all of the colliding objects before the collision will be the same as the total momentum afterwards.
