I need help with this Matlab problem please

The distance a freely falling object travels is

where

g = acceleration due to gravity, 9.8 m/s2

t = time in seconds

x = distance traveled in meters.

If you have taken calculus, you know that we can find the velocity of the object by taking the derivative of the preceding equation. That is,

We can find the acceleration by taking the derivative again:

Create a function called freefall with a single input vector t that returns values for distance x, velocity v, and acceleration g. (Include a commented out copy of the function in your .m file). Make sure the function has a descriptive help and is well documented.

Test your function with a time vector that ranges from 0 to 20 seconds. (Include this code in your .m file)
