$\left( {\text{A}} \right)$ Maximum, Maximum
$\left( {\text{B}} \right)$ Maximum, Zero
$\left( {\text{C}} \right)$ Minimum, Maximum
$\left( {\text{D}} \right)$ None

Answer 1

Hint:Collision: It is the event in which two or more bodies exert forces on each other in about a relatively short period.

Perfectly elastic collision: It is an encounter between two bodies in which the value of the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into any other forms of energy such as heat, noise, or potential energy.

Perfectly inelastic collision: It is defined as the collision between two bodies in which the maximum amount of kinetic energy of a system is lost.

Complete step-by-step solution:
In a perfectly inelastic collision, the colliding particles stick together, i.e., a zero coefficient of restitution.

 In such an inelastic collision, kinetic energy is lost by bonding the two bodies together.
This bonding energy between the bodies usually results in a maximum kinetic energy loss of the system.

Coefficient of restitution (COR): It is defined as is the ratio of the final to initial relative velocity between two objects after they collide. It normally ranges from \[0\] to\[1\]. It is denoted by \[\left( e \right)\].

Hence, the correct option is B

Note:When the value of the coefficient of restitution is \[1\], the collision would be a perfectly elastic collision.
-In an inelastic collision, the momentum and total kinetic energy before and after collision do not remain the same.
-The forces involved during an inelastic collision are non-conservative in nature.
-In an inelastic collision, linear momentum is conserved in.
-Kinetic energy is not conserved due to the action of internal friction in an inelastic collision.
