Not sure if I"m doing this wrong; if there's some special way to calculate air resistance that isn't the formula $W = .5(\text{Mass})(v_f^2-v_i^2)$, with $v_f$ being the final speed and $v_i$ being initial speed.
1 lis 2022 · The formula for calculating work done by air resistance is: W = ½ C A ρ v ^3 t. Where: W is the work done (in joules, J) C is the drag coefficient (dimensionless) A is the cross-sectional area of the object (in square meters, m^2) ρ is the density of the air (in kilograms per cubic meter, kg/m^3)

The first law of thermodynamics relates the internal energy change, work done by the system, and the heat transferred to the system in a simple equation. The internal energy is a function of state and is therefore fixed at any given point regardless of how the system reaches the state.
What is the work done by air resistance on the ball? Assuming that the air resistance performs roughly the same job during the descent, calculate the speed of the ball when it returns to the starting point. How do I calculate the work of the air resistance?
Work is done when a force is used to move an object. The formula for work done is: Work done = force × distance. Where: W = work done in joules (J) or newton-metres (N m) F =force in newtons (N) d = distance in metres (m) You can rearrange this equation with the help of the formula triangle:
