hi, i need answer for this questions please ( see th attchment)
An inelastic collision is a type of collision between two objects where there is a loss of kinetic energy. This means that the total kinetic energy of the system before and after the collision is not the same, and some of the initial kinetic energy is converted into other forms of energy such as heat or sound.
In an elastic collision, the total kinetic energy of the system is conserved, meaning that the total kinetic energy before the collision is the same as the total kinetic energy after the collision. In an inelastic collision, however, there is a loss of kinetic energy and the total kinetic energy after the collision is less than the total kinetic energy before the collision.
The degree of inelasticity in a collision depends on the materials and properties of the objects involved, as well as the angle and speed of the collision. Objects made of more elastic materials, such as rubber, will experience less inelasticity compared to objects made of less elastic materials, such as metal.
Yes, an inelastic collision can be perfectly inelastic, meaning that the two objects stick together after the collision and move as one. This type of collision is often seen in sports such as billiards, where the cue ball sticks to the object ball after impact.
The coefficient of restitution, denoted by the symbol e, is a measure of the elasticity of a collision. In an inelastic collision, the coefficient of restitution is less than 1. The equation for calculating the coefficient of restitution is e = (v2 - v1) / (u1 - u2), where v1 and v2 are the final velocities of the two objects and u1 and u2 are the initial velocities of the two objects.
