Mud thrown on a wall and sticking to it is an example for:
Correct answer: D. Perfectly inelastic collision
- A. Inelastic collision
- B. Elastic collision
- C. Super elastic collision
- D. Perfectly inelastic collision
Explanation
In a perfectly inelastic collision bodies stick together after impact, maximizing kinetic energy loss while conserving momentum. Mud sticking to a wall exemplifies this because the mud's kinetic energy is not recovered and it adheres to the surface.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
