An object is dropped from a bridge. it is recorded to take 3.4 seconds to reach the ground. how high is the bridge? assume the acceleration of gravity is 10m/sec2

The height of bridge is

Explanation:

Given the time taken to reach the ground is

And acceleration of gravity

Also the initial velocity of the object

The object is falling under the condition of free fall.

So, we can use the following formula for computing the distance when the object is under free fall.

Where is the height, is time of fall, and is acceleration of gravity.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
