Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays the distance between them. The formula for computing the distance is √(x2 − x1) 2 + (y2 − y1).

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
