Introductory Newton's 2nd Law Example Problem and Demonstration

The video tutorial demonstrates an example problem using Newton's second law to determine the force of friction between a dynamics cart and a track. The problem involves a cart with a force sensor, and the video guides through setting up the problem, converting units, drawing a free body diagram, and applying Newton's second law. The tutorial calculates acceleration using uniformly accelerated motion equations and solves for the force of friction, highlighting its negligible impact compared to the applied force.

What is the significance of the free body diagram in solving this problem?

What is the calculated force of friction in newtons?

Why can the force of friction be considered negligible in this scenario?
