In an elastic collision momentum is conserved as well as the kinetic energy
Explanation:
In physics, there are two types of collisions:
- Elastic collision: in an elastic collision, the total momentum of the system is conserved, and the total kinetic energy of the system is conserved as well. This is because there are no internal frictions acting on the system, so the energy is conserved. An example of elastic collision is (approximately) that occurring between two billiard balls.
- Inelastic collision: in an inelastic collision, the total momentum of the system is conserved, while the total kinetic energy is not. In fact, due to the presence of internal frictions, part of the total energy is converted into thermal energy and sound during the collision, and therefore "wasted", so the final total kinetic energy is less than the initial one. An example of inelastic collision is the collision between two cars. The maximum amount of kinetic energy is lost when the two objects stick together after the collision; in this case, we talk about perfectly inelastic collision.
Therefore, the complete sentence is
In an elastic collision momentum is conserved as well as the kinetic energy

<span>the amount of water a sponge can absorb depends on many factors. The material the sponge is made out of, the structure of the sponge and the size of the sponge all affect how much water the sponge can absorb.</span>
Answer:
Option D
670 Kg.m/s
Explanation:
Initial momentum is given by mv=82*5.6=459.2 Kg.m/s (taking eastward as positive)
Final momentum is also mv but v being westward direction, we take it negative
Final momentum=82*-2.5= -205 Kg.m/s
Change in momentum=Final momentum-Initial momentum=-205-459.2=-664.2 Kg.m/s
Impulse=change in momentum=664.2 Kg.m/s rounded off as 670 Kg.m/s
