C++ LANGUAGE
The following formula can be used to determine the distance an
object falls in a specific time period:
d = 1 2 g t 2
where d is the distance in meters, g is 9.8, and t is the amount
of time, in seconds, the object has been falling.
Write a function named fallingDistance that accepts an
object's falling time in seconds as an argument. You must
define a named constant for g using a meaningful name and...

7. 0.41 points Tipler8 2.P057 My Notes Ask Your Teacher A submarine can use sonar (sound traveling through water) to determine its distance from other objects. The time between the emission of a sound pulse (a "ping") and the detection of its echo can be used to determine such distances. Alternatively, by measuring the time between successive echo receptions of a regularly timed set of pings, the submarine's speed may be determined by comparing the time between pings....

When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period: d=1/2 gt^2 The variables in the formula are as follows: d is the distance, g is 9.8, and t is the amount of time that the objects has been falling. Write a soldier method that accepts an object’s falling time as an argument. The method should return the distance that the object has fallen...
