## Question:

Programming Exercise 11 in Chapter 6 asked you to design a program that plays the Rock, Paper, Scissors game. In the program, the user enters one of the three strings—"rock", "paper", or "scissors"—at the keyboard. Add input validation (with a case-insensitive comparison) to make sure the user enters one of those strings only.

Programming Exercise 11 in Chapter 6

In physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy:

The variables in the formula are as follows: KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity, in meters per second. Design a function named kineticEnergy that accepts an object’s mass (in kilograms)
and velocity (in meters per second) as arguments. The function should return the amount of kinetic energy that the object has. Design a program that asks the user to enter values for mass and velocity, and then calls the kineticEnergy function to get the object’s kinetic energy.
