A skydiver, who weighs $650 \mathrm{N},$ is falling at a constant speed with his parachute open. Consider the apparatus that connects the parachute to the skydiver to be part of the parachute. The parachute pulls upward on the skydiver with a force of $620 \mathrm{N}$. Consider the skydiver and parachute to be a single system. Identify the external forces acting on this system and draw an $\mathrm{FBD}$.

Key Concepts

Free Body Diagram

A free body diagram (FBD) is a simplified representation of a system where forces acting on the object or system are depicted as arrows. It helps in visualizing all the external forces and in setting up the equations of motion by clearly marking the direction and point of application of forces such as gravity and any resistive forces.

External Forces

External forces are forces that originate from outside the system being analyzed and act upon it. In the context of the problem, they include the gravitational force acting downward on the skydiver and parachute system, and the upward force exerted by the parachute. These forces are crucial for understanding how the system behaves as a whole.

Equilibrium

Equilibrium refers to the condition where all the external forces acting on a system balance each other out, resulting in no net force and, consequently, no acceleration. Since the skydiver is falling at a constant speed, the forces (gravitational and parachute force) are in equilibrium, illustrating this fundamental concept in dynamics.

System Analysis

System analysis involves considering all components of the system collectively to determine the overall effect of external forces. By treating the skydiver and the parachute as a single system, one simplifies the problem and focuses solely on the external forces acting on the combined system rather than internal forces between its parts.
