19. If we drop a rock near the surface of Earth, physics tells us that the distance in feetthat it falls is given by 16t, where t is the number of seconds since the rock wasdropped. Is the distance a rock falls a linear function of the time since it wasdropped? Suggestion: Compare the distance fallen over the first second to thatfallen over the next second.

Answer :

This problem is about functions.

It's important to know that the situation described follows the equation

[tex]16t[/tex]

Which is actually a linear function, since the variable is linear.

Therefore, the answer is yes, the distance is a linear function that depends on time.
