Answer:
1.2 × 10⁻³ J
Explanation:
Given data
- Mass of the raindrop (m): 107 × 10⁻⁶ kg = 1.07 × 10⁻⁴ kg
- Kinetic energy (K): to be determined
We can determine the kinetic energy of the raindrop using the following expression.
K = 1/2 × m × v²
K = 1/2 × 1.07 × 10⁻⁴ kg × (4.7 m/s)²
K = 1.2 × 10⁻³ J
The kinetic energy of the raindrop is 1.2 × 10⁻³ J.
