Homework Help Overview

The problem involves calculating the tension in a rope that is used to pull a 5 kg mass up a 30 degree slope, with a coefficient of kinetic friction of 0.26. The original poster mentions a specific answer but expresses difficulty in arriving at that value.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants question the clarity of the problem setup, particularly regarding the description of the rope and the situation. Some suggest analyzing the forces acting on the mass, while others provide a calculation attempt for tension.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the problem's details and exploring different interpretations of the forces involved. There is an attempt to calculate the tension, but the original poster's confusion remains evident.

Contextual Notes

There is a request for additional information, such as a diagram, to better understand the scenario. The discussion reflects uncertainty about the setup and the forces at play.

Homework Statement


Determine the tension in the rope during the acceleration of a 5 kg mass along a 30 degree slope.
coeffecient of kinetic friction is 0.26

The correct answer is (68 N along the ramp), but I can't seem to get that answer.

Where's the rope? Can you describe the situation more clearly, or attach a diagram?

Any thoughts?
 
You should maybe start by looking at the forces on each of the masses.
 
I think I've figured it out.

T = (ma) + F(pulling back down slope) + F(friction)
T = 67.5344 N rounded to 68 N
