That's the right approach, but I don't understand how you get such a small velocity. Did you forget to convert the area to m2?newbe318 said:
Terminal speed, also known as terminal velocity, is the maximum speed that a falling object, such as a skydiver, can reach when the force of gravity is balanced by the drag force of the surrounding air.
Terminal speed can be calculated by using the equation: Vt = √(2mg/ρACd), where Vt is terminal speed, m is the mass of the skydiver, g is the acceleration due to gravity, ρ is the density of the air, A is the cross-sectional area of the skydiver, and Cd is the drag coefficient.
The terminal speed of a skydiver can be affected by various factors such as the mass and size of the skydiver, the density and viscosity of the air, and the force of gravity. Other factors that can have an impact include the shape and orientation of the skydiver, as well as the presence of any external forces such as wind.
Reaching terminal speed is important for a skydiver because it allows them to experience a smooth descent due to the balanced forces of gravity and air resistance. It also ensures that they do not accelerate to dangerous speeds that could result in injury or harm.
Yes, a skydiver can change their terminal speed by altering their body position or by using a parachute. By changing their body position, they can increase or decrease their surface area, which affects the drag force. Using a parachute increases the surface area and therefore increases the drag force, causing the skydiver to slow down and reach a lower terminal speed.
