your friend says that the heavyweight champion of the world cannot exert a force of 50N on a piece of tissue paper with his best punch. the tissue paper is held in midair- no wall, no tricks. you?

Is "you" the question?

Is the tissue really held?

The claim is probably true when you consider the mass of a tissue (about 0.001 kg) and the maximum acceleration a fist can apply, about 50 m/s^2.

Remember that F = ma

To determine whether the heavyweight champion of the world can exert a force of 50N on a piece of tissue paper with his best punch, we need to consider some basic physics principles.

1. Force exerted by the punch: According to Newton's second law of motion, force (F) can be calculated by multiplying mass (m) and acceleration (a). F = m * a. Since the force exerted by the punch is unknown, let's assume that it is the maximum force that the boxer can generate.

2. Mass of the tissue paper: Tissue paper is very light and has a low mass. Let's assume that the mass of the tissue paper (m) is negligible.

3. Acceleration required: To calculate the acceleration required to exert a force of 50N on the tissue paper, rearrange Newton's second law equation: a = F / m. Since the mass (m) is negligible, the acceleration required will be very high.

4. Limitations: When a punch is thrown, the boxer's fist accelerates while making contact with the tissue paper. However, due to the low mass of the tissue paper, even if the boxer's fist accelerates quickly, it is unlikely to generate a force of 50N on the tissue paper.

5. Air resistance: Additionally, air resistance can also affect the tissue paper's behavior. The movement of the tissue paper in midair may cause it to quickly change direction or fall due to the lack of support from a wall or any other surface.

Considering these factors, it is reasonable to agree with your friend's statement that the heavyweight champion of the world cannot exert a force of 50N on a piece of tissue paper with his best punch when it is held in midair, as the tissue paper is very light and subject to various external forces.

To answer this question, we need to determine the basic principle of force and understand how it relates to the given scenario.

The heavyweight champion's ability to exert force is determined by various factors, such as his strength, technique, and physical capabilities. The force he can generate with his best punch depends on these factors. However, it is highly unlikely for someone to exert a force of 50N on a piece of tissue paper with a punch, regardless of their strength.

Tissue paper is very delicate and lightweight, which means it requires a minimal amount of force to move or tear it. When a force is applied to an object, it experiences acceleration or deformation, according to Newton's second law of motion. However, tissue paper is not rigid enough to withstand a force as high as 50N without tearing or moving significantly.

To visualize this, imagine trying to punch a tissue paper held in midair. The force from the punch would easily push or tear the tissue paper, as it is not designed to withstand strong impacts. Even the lightest punch from the heavyweight champion would likely exceed the tissue paper's threshold.

Hence, based on our understanding of force, tissue paper's fragility, and the nature of punches, we can conclude that the heavyweight champion of the world cannot exert a force of 50N on a piece of tissue paper with his best punch.
