Answers:

In the bouncingballwithimport.mo file, go to text view to see the code.

In line number 3 and 4, replace Modelica.SIunits.Length with Modelica.Units.SI.Length

In line no 5, replace Modelica.SIunits.Velocity with Modelica.Units.SI.Velocity

In line no 6, replace Modelica.SIunits.Acceleration with Modelica.Units.SI.Acceleration

Make these changes, and the model should run fine.
