In Fig. $6-59$, block 1 of mass $m_{1}=2.0 \mathrm{~kg}$ and block 2 of mass $m_{2}=1.0 \mathrm{~kg}$ are connected by a string of negligible mass. Block 2 is pushed by force $\vec{F}$ of magnitude 20 $\mathrm{N}$ and angle $\theta=35^{\circ} .$ The coefficient of kinetic friction between each block $0.20 .$ What is the tension in the string?

Key Concepts

Kinetic Friction

Kinetic friction is the resistive force that opposes the relative motion between two surfaces sliding against each other. It is calculated as the product of the kinetic friction coefficient and the normal force, and it plays a significant role in determining the net force and subsequent acceleration in dynamic systems.

Force Decomposition

Force decomposition involves breaking a force applied at an angle into its horizontal and vertical components. This technique is crucial when dealing with forces that are not aligned with the coordinate axes, ensuring that each component is properly addressed in the analysis of motion.

Free-Body Diagrams

Free-body diagrams are visual tools that help isolate individual objects and display all the forces acting on them. They are essential in identifying and organizing the forces – such as gravitational, normal, frictional, applied, and tension forces – to accurately apply the laws of motion.

Newton's Second Law

Newton's Second Law states that the net force acting on an object equals its mass multiplied by its acceleration. This principle is fundamental for setting up equations of motion for each object in a system and analyzing how various forces, such as applied forces, friction, and tension, affect acceleration.
