Homework Help Overview

The discussion revolves around a physics problem related to force and weight, specifically calculating the weight of an individual and the force required to move that weight up a 70-degree incline. The subject area includes concepts of force, weight, and inclined planes.

Discussion Character

  • Exploratory, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to calculate weight using the formula w=mg and questions the correctness of their result. Some participants confirm the weight calculation and raise further questions about the force needed to move that weight up an incline, as well as the force required for horizontal movement.

Discussion Status

The discussion is ongoing with participants confirming the weight calculation and exploring additional questions about forces on an incline and in horizontal motion. There is no explicit consensus yet on the subsequent calculations or interpretations.

Contextual Notes

Participants are working within the constraints of a homework assignment, which may limit the information available for solving the problem. The original poster's assumptions about the force and its direction are also under discussion.

Homework Statement



Assume that force the force required to walk from home to school is on a 70 degree angle to the horizontal surface. This force is equal to your weight.
mass is 120lb or 48 kg
a) calculate weight.

The Attempt at a Solution



a)
w=mg
w=48kg*9.8N/kg
w=470.4N
IS THAT RIGHT?

470.4 N is the right weight. Now how much for does it take to push that weight up a 70 degree incline? I think that's the question.

b) calculate the mangitude and direction of the force that causes you to move in the horizontal direction.
