SUMMARY

The discussion focuses on calculating speed using Newton's second law of motion, specifically the formula F = m*a. Given a forward force of 5.0 N, a mass of 0.35 kg, and a gravitational force of 2.94 N, participants emphasize determining the net acceleration by considering the direction of gravity. The overall acceleration can then be used in kinematic equations to find the speed. This approach effectively combines fundamental physics principles with practical calculations.

PREREQUISITES
  • Understanding of Newton's second law (F = m*a)
  • Basic knowledge of kinematics
  • Familiarity with forces and their directions
  • Concept of gravitational force and its impact on motion
NEXT STEPS
  • Study kinematic equations for calculating speed and distance
  • Explore vector addition of forces in physics
  • Learn about the effects of gravity on motion in different contexts
  • Investigate real-world applications of Newton's laws in engineering
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in applying Newton's laws to solve motion-related problems.

1. Homework Statement :
Calculate the speed using just the given force (the force which moves forward), 5,0N
The mass 0,35kg
And the gravity: 2,94N How would this be done?

How would this be done?

F = m*a

Determine the direction that gravity affects and then determine the overall acceleration.

The rest is just kinematics.
