Question

A tornado lifts a truck 252 m above the ground. As the storm continues, the tornado throws the truck horizontally. It lands 560 m away from where it was picked up. How fast was the truck traveling horizontally through its flight? Round your answer to the nearest tenth. m/s

Answer 1

Answer:

  78.1 m/s

Explanation:

The time it takes to fall from 252 meters above the ground is about ...

  252 = 4.9t^2

  √(252/4.9) = t = 7.1714  . . .  seconds

Then the horizontal speed is ...

  speed = distance/time

  speed = 560 m/(7.1714 s) = 78.088 m/s

The horizontal speed is about 78.1 m/s.

_____

That's about 281 km/hour.
