Question

A balloon has 2gm of air. If a small hole is pierced into it,the air comes out with a speed of 2m/s. If the balloon shrinks completely in 5secs,the average thrust experienced by the balloon is?

Answer 1

well all Xmasster well all Xmasster

Answer 2

Answer:

The average thrust (force) experienced by balloon is 0.0008 N.

Explanation:

Given;-

     Mass of balloon, m = 2 g

Velocity of air (coming out), v = 2 m/s

     time period, t = 5 s

Let the average force (thrust) be 'F'.

We know that, by formula:-

    Force, F = mΔv/ Δt

               F = 2 × 2 / 1000 × 5

               F = 4/5000

               F = 0.0008 N

Hence, the average thrust or force experienced by the balloon is 0.0008 N.
