Answer 1

4 m/s

Step-by-step explanation:

Step 1: Given data

• Mass of the balloon (m): 400 kg

• Kinetic energy of the balloon (KE): 3200 J

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
