Answer
Here's how to calculate the velocity:1. **Understand the formula:** Kinetic energy (KE) is calculated using the formula KE = 1/2 * m * v², where m is mass and v is velocity.2. **Rearrange the formula:** To find velocity (v), we need to rearrange the formula: v² = 2 * KE / m, and then v = √(2 * KE / m)3. **Plug in the values:** * KE = 25,000 J * m = 50 kg4. **Calculate:** v = √(2 * 25,000 J / 50 kg) = √(1000 m²/s²) = 31.62 m/sTherefore, your velocity as you hit the water is approximately
m/s.
