Terminal Velocity of a skydiver

Click For Summary
SUMMARY

The discussion focuses on calculating the mass of a skydiver approaching terminal velocity, given specific forces acting on her. The fluid friction opposing her descent is 680 N, while the unbalanced force causing acceleration is 40 N. Using the equation Fg = mg, the derived mass of the diver with her gear is approximately 4.08 kg. The conversation also emphasizes understanding the relationship between net force, gravitational force, and frictional force in this context.

Homework Statement


[/B]
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.

Homework Equations

The Attempt at a Solution



My attempt: Fg = mg
Fg/g=m
40/9.8=m
4.08 kg =m

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?
