Homework Help Overview

The problem involves determining the minimum force required to keep a sled moving over a horizontal surface, considering the kinetic coefficient of friction and the mass of the sled. The subject area relates to dynamics and friction in physics.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the calculation of the force based on the coefficient of friction and the sled's mass. Questions arise regarding the units of force and the assumptions made about the mass measurement.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the units of force and confirming assumptions about the calculations. There is no explicit consensus yet, as different interpretations of the unit of force are being explored.

Contextual Notes

Participants note the potential confusion regarding the unit of mass being in slugs versus kilograms, which may affect the interpretation of the force calculation.

Homework Statement


A sled is pulled over a horizontal surface where the kinetic coefficient of friction is .20. What is the minimum force necessary to keep the sled moving if its mass is 2 slugs?


Homework Equations


fs = Ns(mg)


The Attempt at a Solution


fs = (.20) (2 slugs) (32)
=12.8

This problem has got me stumped. Please help! Thank You.
