# Amount of Time

Algebra 2

### Amount of Time

A penny is dropped from the top of the Empire State Building. Determine amount of time for the penny to reach the ground, neglecting air resistance.

The building is 1250 ft. in height.

Unsure how to solve.

### Re: Amount of Time

There is second formula (2) at the link that is higher sentence.
IF I don't mistake, r(0) - lenth , has been gone before measuaring.r(0) = 0.
Then $$\nu$$(0) - starting speed .$$\nu$$(0) = 0.
a = g - acceleration of gravity.

At last find t .
That's all : .

### Re: Amount of Time

S = $$\nu$$ * t + a * t^2 / 2

IF I don't mistake, $$\nu$$ - starting speed . $$\nu$$ = 0 in the exersize.
a= g- acceleration of gravity.
At last find t .
