How Is Work Done by Air Resistance Calculated in a Falling Raindrop Scenario?

[PepeF.]

Homework Statement

a .459kg raindrop falls vertically at constant speed under the influence of gravity and air resistance. acceleration due to gravity is 9.8 m/s

after the drop 141 m, the work done by gravity is 634.246 J

a problem ask the work donde by air resistance
the work done by gravity is 634.246J

Homework Equations

i just know regular force and work

w=f*change in x/y
f= m*g

The Attempt at a Solution

i don't know what to do

Hi PepeF.!

Hint: use the work-energy theorem …

total work done = change in kinetic energy ​
