SUMMARY

The discussion focuses on interpreting a momentum graph to determine the object's momentum at 3 seconds, which is exerting a force of 35 Newtons. The participant initially calculated the momentum as 105 kg·m/s but received a mark indicating the answer was incorrect. The correct approach involves calculating the area under the graph between t=1 and t=3 seconds, which consists of a rectangle and a triangle, to accurately determine the change in momentum.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Familiarity with momentum calculations
  • Knowledge of graph interpretation techniques
  • Basic skills in geometry for area calculation
NEXT STEPS
  • Study the principles of Newton's Second Law of Motion
  • Learn how to calculate momentum from force and time
  • Explore techniques for calculating areas under graphs
  • Practice interpreting various types of motion graphs
USEFUL FOR

Students studying physics, educators teaching momentum concepts, and anyone interested in mastering graph interpretation in mechanics.

Homework Statement



What is the objects momentum at 3 seconds, on the graph at 3 seconds it is exerting 35n

Homework Equations



f=change in momentum/time

The Attempt at a Solution


I got 105kgms but it was marked wrong...
I can make the graph in paint if it will help anybody.

It would be beneficial to post the graph as well.
 
ok:

then simply the area under the graph gives the change in momentum, so from t=1 to t=3 find the area. It forms a rectangle and triangle.
