SUMMARY

The discussion centers on calculating velocity using the equations of motion, specifically F=ma, a=F/m, and V^2 = Vinitial^2 + 2a(x_final - x_initial). A participant calculated acceleration as 0.117647 m/s² by dividing force (0.2 N) by mass (1.7 kg) and subsequently used this value to find velocity, resulting in 0.572 m/s. However, the participant expressed uncertainty about the accuracy of their calculations and the application of the equations, indicating a potential error in their approach.

PREREQUISITES
  • Understanding of Newton's Second Law (F=ma)
  • Basic knowledge of kinematic equations
  • Ability to perform algebraic manipulations
  • Familiarity with units of measurement in physics (N, kg, m/s²)
NEXT STEPS
  • Review the derivation and application of kinematic equations
  • Practice problems involving force, mass, and acceleration calculations
  • Learn about the implications of unit conversions in physics
  • Explore common mistakes in physics calculations and how to avoid them
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in mastering the application of Newtonian physics principles.

2. F=ma, a=F/m, V^2 = Vinitial^2 + 2a(x_final - x_inital)



3. I got an acceleration at .84 by doing a=.2/1.7, which came out to be .117647 m/s^2, which I plugged into the v equation for √.44^2+.2*.117647+.57 which gave me an answer of .572 m/s. I haven't plugged it in yet because I lose points if it is wrong so I just wanted to verify my work here.

And then I wasn't sure how to do the second one

I did put in that .572 and that was the wrong answer so I'm not sure if I had the wrong equation or just did incorrect calculations.
