I discuss a particle with a mass of 5 kg being pulled on a rough horizontal plane with a force of 28 Newtons, leading to a calculated friction force of 21 Newtons and a coefficient of friction of 0.43. I also analyze a 20 kg crate being pulled along a rough floor, resolving forces to find the normal reaction and the resulting acceleration of 0.396 m/s². I highlight how changing the direction of the applied force affects the acceleration and friction. Viewers are encouraged to engage with the material and practice similar problems."}
