Homework Help Overview

The problem involves calculating the power generated by a force acting on a 1100 kg object being pulled at a constant velocity of 5 m/s across a horizontal surface. The force is applied at a 37-degree angle above the horizontal.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants discuss the relationship between power, force, and velocity, with one suggesting the formula power = force x velocity. There is uncertainty about the simplicity of this approach and the need for free body diagrams to analyze the forces involved.

Discussion Status

Some participants have attempted to apply the power formula but express doubt about its adequacy. There is an ongoing exploration of the need for free body diagrams and a deeper understanding of the forces at play.

Contextual Notes

One participant notes the formula for work and suggests solving for distance by assuming the mass starts from rest, indicating a potential consideration of initial conditions in the problem.

A 1100 kg object is pulled across a horizontal surface at a constant velocity of 5 m/s. What is the power generated by this force? (Picture includes object being pulled at a 37 degree angle above the horizontal with a Force of 122 N)

Please list what you believe are the relevant equations and show some attempt at a solution. Thanks.
 
Well I thought that power just = force x velocity, so (122)(5) = 610 watts. However I really don't think its that simple. I don't understand how to do any free body diagrams for this problem, though I feel they are needed.

Uhe formula for work: W = Fdcos37*, solve for d by assuming that the mass starts from rest.
