Falling Distance
Question:
When an object is falling,
the following formula can be used to determine
the distance the object falls in a specific
time period:
d = 1/2 gt2
The variables in the formula are as follows:
- d is the distance in meters,
- g is a constant (9.8), and
- t is the amount of time
in seconds, that the object has been falling.
Question:
Write a program that accepts falling time
of an object in seconds. Your program should
contain a function to calculate the result and
the function should return the distance
in meters, that the object has fallen during
that time interval.
Input specification
In the first line, program will get a number
t (time) 0 < t <1000.
Output specification
Print out just one floating point number
which is the distance that the object
has fallen through the given time interval.
