C++ language

b) Using the stack and instruction pointer, describe what happens when a program running on a personal computer calls a function and how the function returns a value. (7 marks) c) Create a program that determines how quickly an object is travelling when it hits the ground. The user will enter the height from which the object is dropped in meters (m). Because the object is dropped its initial speed is Om/s. Assume that the acceleration due to gravity is 9.8m/s^2. You can use the formula vf v2 + 2ad to compute the final speed, vf, when the initial speed, vi, acceleration, a, and distance, d, are (10 marks) known. JESTION 6
