A ball is dropped off the side of a bridge after 1.55 seconds how far has it fallen (units=m)

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 :

Put u = 0 and a = g

So,

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

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
