Ecceleration help

  1. Oct 24, 2009 #1
    I am working on a project of my own and need a little help. I am writing a program in Visual Basic that involves some precise calculations of Acceleration. I have looked over quite a bit of information and examples on the web and I am more confused now than when I started. I am sure you all have been here at one point or another.

    Basically I need to

    1: Find the Time it takes to accelerate at a specified rate to a specified velocity from specified velocity.

    2: Find the distance it takes to accelerate at a specified rate from a specified velocity to specified velocity

    Below is what I have been playing around with in VB. I think I have confused my self.

    'in inches per second/second
    Dim MaxAcceleration As Double = 200

    'in seconds
    Dim MaxAcceltime As Double

    'in inches
    Dim MaxAcceldistance As Double

    'inches per second/second
    Dim MaxVelocity As Double = 6000
    Dim SetVelocity As Double = 20
    Dim IntVelocity As Double = 0
    Dim AverageVelocity As Double

    ' The time it takes to go from 0 to Max Velocity in seconds
    'Max Acceleration time
    MaxAcceltime = ((MaxVelocity - IntVelocity) / MaxAcceleration)

    ' I get 30.0

    ' The Average Velocity
    AverageVelocity = ((IntVelocity + MaxVelocity) / 2)

    'I get 3000.0

    'The distance required to go from 0 to Max Velocity
    'MaxAccel Distance in inches
    MaxAcceldistance = (AverageVelocity * MaxAcceltime)

    ' I get 90000.0

    Nice work, bsharp. Your equations and answers are correct.

    Looks good...

    But you might want to edit the comment line on your velocity variables...

    units should be inches per second.

    Thank you for the reply's. Some times thinking your incorrect and actually being correct is just as bad as thinking your correct and being incorrect. Although I guess it saves on finding out later on.
