Answer:

d = 11.77 m

Explanation:

Given that,

A ball is droped off the side of a bridge after 1.55 seconds.

We need to find how far it has fallen.

It will fall under the action of gravity. It would mean that a = g = 9.8 m/s²

Let it is fallen at a distance d. d can be calculated using second equation of motion as follows :

[tex]d=ut+\dfrac{1}{2}at^2[/tex]

Put u = 0 and a = g

So,

[tex]d=\dfrac{1}{2}\times 9.8\times (1.55)^2\\\\d=11.77\ m[/tex]

Hence, it will fall at a distance of 11.77 m.
