Question

5. A helicopter scoops a load of water out of a lake, to dump on a forest fire. The helicopter exerts 6480

N of force on the water while rising high enough to fly over a mountain. If the helicopter does 1.62 x
10%) of work on the water while lifting it, how high does it lift the water.

Answer 1

h = 250 m

Step-by-step explanation:

Given that,

The helicopter exerts 6480 N of force on the water while rising high enough to fly over a mountain.

The helicopter does
`1.62* 10^6\ J` of work on the water lifting it.

We need to find how high does it lift the water. Work done is given by :

`W=Fh\\\\h=(W)/(F)\\\\h=(1.62* 10^6)/(6480)\\\\h=250\ m`

So, it can lift the water to a height of 250 m.
