The scenario describes a skydiver who experiences changing speeds and eventually reaches a terminal velocity. Here’s a breakdown of the events in the scenario:
-
Acceleration Phase: The skydiver accelerates from rest, increasing his speed to 20 m/s and then to 30 m/s. During this phase, the force of gravity is greater than the air resistance, leading to an increase in speed.
-
Deceleration of Acceleration: As the skydiver continues to fall, the air resistance (drag) starts to increase as his speed increases. This results in a gradual decrease in his acceleration.
-
Constant Speed (Terminal Velocity): Eventually, the forces acting on the skydiver become balanced. The weight of the skydiver (due to gravity) is equal to the force of air resistance. At this point, he reaches a constant speed of 50 m/s, known as terminal velocity.
In conclusion, an accurate statement summarizing these events could be:
"The skydiver accelerates initially due to gravity, reaches higher speeds as the air resistance increases, and ultimately attains a constant speed of 50 m/s when the force of gravity is balanced by the air resistance."
