SUMMARY
The discussion focuses on solving the motion of a 2 kg fan-cart subjected to a 4 N forward force from the fan and a 1 N frictional force. Using Newton's Second Law, the net force acting on the cart is calculated as 3 N, resulting in an acceleration of 1.5 m/s². The velocity after 3 seconds is determined to be 4.5 m/s, while after 5 seconds, it reaches 7.5 m/s. Displacement calculations reveal that between 3 and 5 seconds, the cart travels 11.5 meters, and the total displacement from 0 to 5 seconds is 18.75 meters, with an average velocity of 5.25 m/s during that interval.
