Chapter 18, Problem 12ICA
Write a program that will allow the user to type the input power of a motor in watts, the mass of an object in kilograms, the height to which the object will be raised by the motor in meters, and the time it took to raise the object in seconds. Use this information to determine the efficiency of the motor. Display the calculated value in the Command Window in the following format, using one decimal place: “The motor is __% efficient.”
