Calculate the kinetic energy of a 107, mg raindrop moving at a speed of 4.7 - Round your answer to 2 significant digits.

1.2 * 10⁻³ J

Explanation:

Given data

Mass of the raindrop (m) : 107 * 10⁻⁶ kg = 1.07 * 10⁻⁴ kg Speed (v) : 4.7 m/s 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.
