(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A fire helicopter carries a 625 kg empty water bucket at the end of a cable 21.7 m long. As the aircraft flies back from a fire at a constant speed of 36.6 m/s, the cable makes an angle of 35.3° with respect to the vertical. Calculate the force of air resistance on the bucket.

2. Relevant equations

F=ma.

F_{net}=0

3. The attempt at a solution

I started with the rationalization that constant speed implies 0 acceleration, meaning F_{net}=0 in both the x and y direction.

Dividing the forces up into F_{nety}=T(tension in the cable)-W(mg)

and F_{netx}is where I get stuck. If the acceleration is 0, then which force is opposing air resistance?

Should I be calculating the horizontal component of the displacement from the vertical?

Help, please!
