The physics
Dropped from rest, an object gains the same amount of speed every second, so its speed after t seconds is v = g·t. The distance adds up all the speed gained so far, so it grows with the square of the time: d = ½·g·t².
Speed after falling for 10 seconds (no air resistance)
Answer: speed = 98.07 m/s (distance fallen 490.33 m, speed 353 km/h).
What we know
- Fall time: 10 s
Step by step
- Given
- t = 10 s
- Formula
- v = g·t
- Substitute
- v = 9.80665 × 10
- Result
- v = 98.07 m/s
