1)Modify the Module 5 Car class to provide a start() method

Resolved Question:

1)
Modify the Module 5 Car class to provide a start() method that
overrides the Vehicle class start() method and a speedUp() method that
overloads the Vehicle class speedup() method.
The initial code for the Car and Vehicle classes, and the TestCar2 driver class from
Module 5 is shown below.

System.out.println(myCar2.toString());
myCar2.speedUp(5.0, 2);
}
}

The Car class’s
overriding start() method must start a car in a southerly direction at zero
speed. The Car class’s overloaded speedup() method should just accept the additional
miles per hour that the car should start moving from its current speed. Modify the
TestCar2 driver class to form a new TestCar3 driver class that creates a myCar3 instance and uses single start() and single speedup() method calls to use the Car class’s start() and speedup() methods only to accelerate it by 50 mph.

Be sure that you include the course, the program number, your name, and the date in your program header. Include additional comments as necessary and maintain consistent
indentation for good programming style as shown in the text. Be sure that you capture
all of your output for this program's execution for full credit
