ME$400-$ Computer Applications in Mechanical Engineering

Exercise #$1$

Instructions:

Complete each of the following steps. When you have completed all steps

assigned, upload the files associated with the exercise on Canvas. Make sure

the filenames you upload as part of your exercise submission have the exact

names specified in each steps of this exercise. If the filenames do not match

exactly, then you submission will not be graded.

Problem $1$

Consider a ball of mass m that is thrown upward at time $=0$ with an initial velocity $(0).$

Assume that the velocity and height can be calculated using the following equations:

$()=(0),$

$()=(0)2/2,$

where $=9\mathrm{.}81/2$ is the accelerations of gravity. Write a program, which meets the

requirements listed below, to calculate the velocity $()$ and the height $()$ at time $.$

Requirements

$1.$ Create a sub directory named $$ex$01$a$,$ and an associated C$++$ source file named

$$ex$01$a$.$cpp$,$ in your CPP directory on the Z: drive.

$2.$ Declare a variable $$ as an integer, and variables $,0,,$ and $$ as floats.

$3.$ Assign a value of $9\mathrm{.}81$ to the variable $.$

$4.$ Prompt the user to enter the initial velocity in meters$/$second$.$ Capture the user

input using the $$ stream object and store the resulting value in the variable $0.$

$5.$ Prompt the user to enter the time that has passed in seconds. Capture the user

input using the cin stream object and store the resulting value in the variable $.$

$6.$ Calculate the velocity $()$ after $$ seconds and store the value in the variable $.$

$7.$ Calculate the height $()$ after $$ seconds and store the value in the variable $.$

$8.$ Using the cout stream object output the values of v$($t$)$ and h$($t$)$ in the following

format:

$$The velocity after time ### seconds is ###$.$# meters$/$s$$

$$The height after time ### seconds is ###$.$# meters$\backslash$
