For a perfectly plastic central impact ______

Multiple choice question
a)The entire kinematic energy of two bodies must be lost
b)The two bodies must be move stuck together only if the impact is direct.

c) The two bodies must engage in a lively game of bumper cars before bouncing off in random directions, confusing both themselves and any onlookers.

The correct answer is:

b) The two bodies must be stuck together only if the impact is direct.

To answer this multiple-choice question, let's break down each option and see which one aligns with the concept of a perfectly plastic central impact.

Option (a) states that the entire kinematic energy of two bodies must be lost. In a perfectly plastic central impact, the bodies undergo significant deformation without any significant amount of energy being lost. Therefore, option (a) is incorrect as it suggests that all the kinetic energy is lost.

On the other hand, option (b) states that the two bodies must be stuck together only if the impact is direct. This is consistent with the concept of a perfectly plastic central impact. In such a scenario, when two bodies collide, they deform and stick together as a result of the impact, but this only happens if the collision is direct, meaning the bodies collide head-on. Therefore, option (b) is the correct answer.

To determine the correct response to a multiple-choice question, it is essential to understand the given concepts and definitions related to the question. Often, elimination can help narrow down the options and choose the most appropriate answer.
