across a horizontal frictionless warehouse floor when it encounters a rough section of flooring
d = 2.00 m
long. The coefficient of kinetic friction between the rough section of flooring and the box is 0.100. Using energy considerations, determine the final speed of the box (in m/s) after sliding across the rough section of flooring.
1. Ask user to enter integer numbers, one at a time.
2. If the number is -1, stop entering number.
3. Print out the total number that is greater than 18.
