A ball is dropped off the side of a bridge. After 1.55 s, how far has it fallen? (Unit=m)

a=-9.80 m/s^2

false

explanation:

boats, things on boats luggage are way more heavy then water.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption
