A cyclist coasting on a level road slows from a speed of 10 mi/hr to 2.5 mi/hr in one minute. Write a computer program that calculates the cyclist’s constant rate of acceleration and determines how long the cyclist will take to come to rest, given an initial speed of 10 mi/hr. (Hint: Use the equation

where a is acceleration, t is time interval, vi is initial velocity, and vf is final velocity.) Write and call a function that displays instructions to the program user and a function that computes a, given t, vf , and vi .
