Homework Help Overview

The discussion revolves around calculating the force required to lift a box weighing 2000N with an upward acceleration of 8 m/s². The context includes considerations of forces acting on the box, including gravitational and frictional forces.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the application of Newton's second law, questioning how to set up the equation for net force when lifting the box. There is a focus on identifying the relevant forces acting on the box during the upward motion.

Discussion Status

Some participants have provided guidance on developing the equation for applied force based on the net force and acceleration. There is an acknowledgment of differing interpretations of the problem's information, but no explicit consensus has been reached.

Contextual Notes

One participant notes that some information in the problem may not be directly relevant, indicating potential confusion regarding the setup. The discussion includes an emphasis on identifying all forces acting on the box during the lifting process.

A box weighs 2000N and is accelerated uniformly over a horizontal surface at a rate of 8 m/s^2. The opposing force of friction between the box and the surface is 27.4 ..

How much force would be required to lift the box upward with an acceleration of 8 m/s^2?

I know that the answer is 3,630N .. but I'm not sure how to get there?

Some of the information in the question doesn't relate to the problem, but anyways, this is an application of [itex]F_{net}=ma[/itex]. You know mass and acceleration, now what is the net force acting on the object while it is moved upward? Develop the equation and solve for applied force.

What forces act on the box when you lift it? Set the net force equal to ma (Newton's 2nd law).
 
Ok got it =D thankyou
