Homework Help Overview

The discussion revolves around a physics problem involving forces, specifically the net force acting on a quarterback tackled by a linebacker. The subject area includes concepts of force, mass, and acceleration in the context of a collision scenario.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the calculation of acceleration based on the force exerted by the linebacker and question the relevance of this calculation to finding the net force on the quarterback. There is also a discussion about the clarity of the problem statement and the assumptions being made regarding the forces at play.

Discussion Status

The discussion is ongoing, with participants questioning the assumptions made in the original problem statement and seeking clarification on the relevance of certain calculations. Some guidance is offered regarding the need for a clearer problem statement to facilitate understanding.

Contextual Notes

There are indications that the original problem statement may be incomplete, leading to confusion about the forces acting on the linebacker and the quarterback. Participants note the unrealistic nature of the force value provided in the problem.

A linebacker has a mass of 110 kg, and he takes off when the ball is snapped and tackles the Q.B of a constant net force of 3.7 * 10^4 N. What is the net force that acts on the 92 kg Q.B.

I know the answer, I just want to see if you can do it.

Why don't you show us how you solved it?
 
Ok. a= 3.7 * 10^4 N/ 110 kg= 336.3 m/s^2

F=92 kg * 336.3 m/s^2=30945.4 N

Why are you calculating the acceleration of the linebacker? (I assume that's what you're doing.) Are you assuming that the 3.7 * 10^4 N force is the only force acting on the linebacker?

Your problem statement in your first post seems truncated--so it's unclear what the full problem is.
 
although it isn't possible for a person to generate that much force, it's just a calculation.

I changed up an original problem I had.

Why don't you restate the problem as fully as possible. (If you want the net force on the QB, then the acceleration of the linebacker seems irrelevant.)
