Average Acceleration Program

Average Acceleration is a physics concept. It describes the rate at which velocity changes over time. You can find average acceleration by knowing velocity and time at two different times.

For instance, if velocity is 30mph at 1:06pm and 70mph at 1:09pm, you can find average acceleration.

• You know that the velocity went from 30 to 70. This is a change of 40.
• You know that the time went from 1:06 to 1:09. This is a change of 3 minutes.

To find average acceleration, you divide change in velocity by change in time.

40 / 3 = 13.33333mph / min

Assignment: Write a program in which you:

Declare the following variables as INT type:

• t1 (stands for time measurement #1)
• t2 (time measurement #2)
• v1 (velocity #1)
• v2 (velocity #2)
• deltaV (delta = change….deltaV = change in velocity)
• deltaT (change in time)
• aa (average acceleration)

Initialize all variables to zero. (See the code list 3-1 on pg. 33 of your text for an example of declaring and initializing a variable. An example was also given in Lesson 2 notes.)

Use the cout statement to describe the concept of average acceleration to the user. Print the blue text from above on your output screen using appropriate line breaks.

Use prompt / cin method to acquire variable values from the user (standard input or keyboard) for: t1, t2, v1, and v2.

Show your variable values on the screen, including the values for deltaV, deltaT, and aa which have not yet been calculated.

When complete, you program should resemble the following (Numbers in red are entered by user):

Average Acceleration is a physics concept. It describes the rate at which velocity changes over time. You can find average acceleration by knowing velocity and time at two different times.

Enter the first time (in minutes): 55

Enter the second time (in minutes): 58

Enter the first velocity (in mph): 40

Enter the second velocity (in mph): 100

You entered the following information:

Time 1 = 55

Time 2 = 58

Velocity 1 = 40

Velocity 2 = 100

Calculations:

Change in Velocity = 0

Change in Time = 0

Average Acceleration = 0

Create a folder called physics. When complete, compile the program, save, and re-compile to create EXE.

Do yourself a favor and start from scratch. If you can complete this assignment with little difficulty, you should be able to get at least a ‘D’ on the upcoming quiz.
