Find the force applied to you by the rubber bands?

Click For Summary
SUMMARY

The problem involves calculating the force exerted by rubber bands when launching a person with a mass of 70 kg and an upward acceleration of 15 m/s². Using Newton's second law, the net force (F) is calculated as F = ma, resulting in a net force of 1050 N. However, this value represents the net force acting on the individual, not the total force exerted by the rubber bands. A free body diagram is essential to identify all forces acting on the individual, including gravitational force.

PREREQUISITES
  • Understanding of Newton's second law of motion
  • Ability to calculate net force using F = ma
  • Knowledge of free body diagrams
  • Basic concepts of gravitational force
NEXT STEPS
  • Study how to draw and interpret free body diagrams
  • Learn about gravitational force calculations
  • Explore the concept of net force versus applied force
  • Review examples of force calculations in physics problems
USEFUL FOR

Students preparing for physics exams, particularly those focusing on mechanics and force calculations, as well as educators teaching these concepts.

Homework Statement



A giant rubber band is going to launch you straight upwards. Upon launch your acceleration is 15 m/s^2 upwards. If your mass is 70 kg, find the force applied to you by the rubber bands.

This is a copy word from word of the problem. Please be specific. I have a physics test tomorrow.

Thanks!


Homework Equations





The Attempt at a Solution



a = 15 m/s^2
M = 70 kg
F = ?

F = ma
F = (70 kg)(15 m/s^2) = 1050 N

F = ma
F = (70 kg)(15 m/s^2) = 1050 N
That's the net force on you during the acceleration, not the force from the rubber band.

Draw a free body diagram of you. What forces are acting? Which way do they act?
 
I do not know. I am looking but can't figure it out.
