Calculate Lift Force of 4510 kg Helicopter Accelerating Upward

Click For Summary

Homework Help Overview

The discussion revolves around calculating the lift force exerted on a helicopter with a mass of 4510 kg that is accelerating upward at 2.1 m/s². Participants are exploring the application of physics principles to determine the required force in Newtons.

Discussion Character

  • Exploratory, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the relevance of Newton's Second Law of motion and its application to the problem. There are inquiries about the equations of motion and attempts to relate net force to mass and acceleration.

Discussion Status

The conversation is ongoing, with some participants suggesting the use of Newton's Second Law while others express uncertainty about how to proceed after calculating the net force. There is no explicit consensus yet on the next steps or the final calculation.

Contextual Notes

One participant notes that they have reviewed the equations in their textbook but found none that seem applicable to this specific problem. This suggests potential constraints in the resources available to them.

A 4510 kg helicopter accelerates upward at 2.1 m/s^2. What lift force is exerted by the air on the propellers?

The answer is in Newtons.

If you can give me an equation, that would be great. Thanks

What have you tried? I would think your book or instructor would have given you some equations of motion. Nothing?
 
I looked through all equations in the chapter and none seem to fit.
 
How about Newtons' Second Law of motion?
 
k Newton's second law

a = Fnet/m

so 2.1 = Fnet/4510 and for Fnet you get 9471 but what then
