The braking distance of a car depends on its speed as the brakes

are applied and on the car’s braking efficiency. A formula for the

braking distance is

bd =s^2/ 2Rg

where bd is the braking distance, s is the car’s speed, R is the braking efficiency and g is

the acceleration due to gravity (9.81). A script has been written that calls a function to

prompt the user for s and R, calls another function to calculate the braking distance, and

calls a third function to print the braking distance in a sentence format with one decimal

place. You are to write a function stub for the function that prompts for s and R, and the

actual function definitions for the other two functions.
