EE 160 Homework 9- Building-up a program... one layer at a time Background: An aircraft reaches a cruising speed of 180 m/s (meters per second), and the engine throttles are set so that the power level is increased. The aircraft then starts to accelerate but the faster it goes, the more aerodynamic drag it experiences (in proportion to the square of the air speed). Eventually, the aircraft reaches a new top speed when the thrust force equals the aerodynamic drag. The equations used to estimate the velocity and acceleration of the aircraft from the time that the throttle is reset until the plane reaches its new cruise speed is as follows: Velocity = 0.000001 time! -0.00488 time? +0.75795 time + 181.3566 Acceleration = 3-0.000062 Velocity? Velocity is in units of m/s, Acceleration is in m/s and time is in's Instructions: 1. Basic pseudocode & flowchart - Write pseudocode to ask the user to enter a time value in seconds. Compute & display the velocity and acceleration for that given time value. Assume the user enters in a time value between 0 and 120 seconds. Complete the flowchart for the above. 2. Basic code - Write the code, compile and test it. Save and submit this Code as hwa.c 3. Error-handling stage? - Build on the existing code. Display an appropriate error message to the user if the input time is negative or above 120 seconds. Save this "enhanced Ccode, compile and run it to test it. Save and submit this Code as hwb.c 4. Even more error handling - Display an appropriate error message to the user if a non-numerical input is entered (using isdigit() command). Write the code, compile and test it. Save and submit this C code as hw9c.c Use a Test-dataset - when all the above coding specs are complete, you can test the code for your hw9c.c using the following test dataset Submit the run-output so that it can be graded: Time input of 0.23 seconds Time input of 3.891555666 seconds Time input of 25 seconds Time input of -3 seconds, Time input of 12000 seconds Time input of "abc Deliverables: This homework is due Friday 2/19 by the end of class.
