Question

a. a three story building
b. a one story building
c. a two story building

Answer 1

If you were to have an accident while driving without a seatbelt at 30 miles per hour, you would hit the dashboard or the windshield with a force comparable to falling from a significant height. In this case, the correct answer is:

c. a two story building.

Generally, hitting the dashboard at this speed can be roughly equated to falling from about a two-story building, as both involve a similar amount of kinetic energy and the impact force generated upon collision.
