Your diver has a force acting against gravity. The net force is 40N, how would you find the gravitational force knowing the net and frictional force?Shellina said:Homework Statement

A skydiver, initially undergoing a high acceleration, is approaching her terminal velocity. At a given
instant, the fluid friction (due to air resistance) on the diver and her diving gear is 680. N [up] and the
unbalanced force causing the acceleration is 40. N [down]. Find the mass of the diver with her gear.

The Attempt at a Solution
My attempt: Fg = mg
Fg/g=m
40/9.8=m
4.08 kg =m
Terminal Velocity is the maximum velocity that a falling object, such as a skydiver, can reach when the force of gravity is balanced by the force of air resistance.
Terminal Velocity is calculated by using the equation: Vt = √(2mg/ρAC), where Vt is the terminal velocity, m is the mass of the object, g is the acceleration due to gravity, ρ is the density of the air, A is the cross-sectional area of the object, and C is the drag coefficient.
The factors that affect the Terminal Velocity of a skydiver include the weight and size of the skydiver, the density and composition of the air, and the position and shape of the skydiver's body during freefall.
Yes, the Terminal Velocity of a skydiver can change during the jump. As the skydiver falls, the air density and composition can change, affecting the drag force and therefore the Terminal Velocity. Additionally, the skydiver can change their body position to alter the air resistance and change their Terminal Velocity.
The average Terminal Velocity of a skydiver is approximately 120 miles per hour or 193 kilometers per hour. However, this can vary depending on the factors mentioned above.
