Question

if a truck falls for 33 seconds after it drives off a bridge into canyon below. how far does it fall before it hits the canyon floor? give your answer in meters.

Answer 1

Here's a formula that's so useful, you should memorize it:

Distance = (1/2) · (acceleration) · (time squared)

On Earth, acceleration of gravity is 9.8 m/s² .

Height of the bridge over the canyon =

Distance the truck falls = (1/2) · (9.8 m/s²) · (33 sec)²

Distance = (4.9 m/s²) · (1,089 sec²)

Distance = 5,336 meters
