Type the correct answer in the box. What's the velocity of the balloon? Use V=VKE
A hot air balloon with a mass of 400 kilograms moves across the sky with 3,200 joules of kinetic energy. The velocity of the balloon is meters/second.

4 m/s

Explanation:

Step 1: Given data

Step 2: Calculate the velocity (v) of the balloon

The kinetic energy is the energy that the balloon has due to its movement. We can calculate the velocity of the balloon using the following expression.

v = √(2 × KE/m)

v = √(2 × 3200 J/400 kg) = 4 m/s
