A fire helicopter carries a bucket of water

In summary, the conversation discusses a fire helicopter carrying a bucket of water at the end of a 20.0 m long cable. The empty bucket has a mass of 580 kg and as the helicopter flies back at a constant speed of 49.5 m/s, the cable makes an angle of 35.0 deg with respect to the vertical. The conversation then moves on to determine the force of air resistance on the bucket and the mass of the water in the bucket after it is filled with sea water and the helicopter returns to the fire at the same speed, but with the bucket making an angle of 6.30 deg with the vertical. Various equations are mentioned, but the conversation ends with the suggestion to use a diagram to

Homework Statement


A fire helicopter carries a bucket of water at the end of a cable 20.0 m long. The empty bucket's mass is 580 kg. As the aircraft flies back from a fire at a constant speed of 49.5 m/s, the cable makes an angle of 35.0 deg with respect to the vertical.
a) Determine the force of air resistance on the bucket. Use g=9.81 m/s2.

b) After filling the bucket with sea water, the pilot returns to the fire at the same speed with the bucket now making an angle of 6.30 deg with the vertical. What is the mass of the water in the bucket?



Homework Equations


f=ma
Vf^2=Vi^2-2ad
mgsinX
ax=gsinX




The Attempt at a Solution


i found acceleration using Vf^2=Vi^2-2ad then i made
Fa-mgsinx=ma
but... i"m not getting the right answer!
b)i would use the same equation as a?

You found the acceleration of what?

A diagram containing the forces acting on the bucket may help. Right now you seem confused about what is going on.
 

1. How much water can a fire helicopter carry in its bucket?

A typical fire helicopter can carry between 600 to 2,000 gallons of water in its bucket, depending on its size and capacity.

2. How does a fire helicopter refill its water bucket?

A fire helicopter can refill its water bucket from a nearby water source, such as a lake, river, or portable water tank. Some helicopters also have the capability to refill from swimming pools or even the ocean.

3. How accurate is a fire helicopter when dropping water on a fire?

A fire helicopter is equipped with precision technology that allows it to accurately drop water on a fire. The pilot uses a GPS system to guide the helicopter to the exact location of the fire and can control the drop rate and flow of water to target specific areas.

4. Can a fire helicopter only carry water in its bucket?

No, in addition to water, a fire helicopter can also carry other fire retardant materials, such as foam or gel, which can be more effective in certain fire situations. Some helicopters also have the ability to carry medical supplies or equipment for rescue operations.

5. How long does it take for a fire helicopter to fill its water bucket?

The time it takes for a fire helicopter to fill its water bucket varies depending on the size of the bucket and the water source. On average, it takes about 30 seconds to fill a 600-gallon bucket from a lake or river, and about 60 seconds from a portable water tank.
