Problem 2: RunwayLength class (RunwayLength.java) Description: Given an airplane's accelation a and take-off speed , you can compute the minimum runway length needed for an airplane to take off using the following formula: length = 2a Write a Java program that prompts the user to enter v in meters/second(m/s) and the acceleration a in meters/second squared(m/s2), and displays the minimum runway length. Please format your output so that the output floating-point number is of scale of 2 (with 2 digits after the decimal point). Outputs: Your output should look similar as follows. $ java Runway Length Please enter the speed and acceleration: 60 3.5 The minimum runway length for this airplane is: 514.29 Problem 3: FeetToMeters class (FeetToMeters.java) Description: Write a program that reads a number in feet, converts it to meters, and displays the result. One foot is 0.305 meter. Please format your output so that the output floating-point number is of scale of 2 (with 2 digits after the decimal point). Outputs: $ java Feet ToMeters Please enter a value for feet: 16.5 16.5 feet is 5.033 meters
