The App - The Physics of the 1974 Mtcars

This Application Will Allow the User to:

* Develop a Table of Physical Quantities for the 1974 mtcars

* Analyze the 1974 mtcars with respect to their physical quantities using bargraphs

* Calculate Braking Distance and Braking time for a selected 1974 model and Braking Force, while traveling at top speed
