    the equation is its for getting the height of fluid after 40 seconds

    h(40) = (.00001)(208953000)/(1000)(9.81)-((.00001)(208953000)/(1000)(9.81)-.092)e^-(1000)(9.81)/(208953000)(.02043)(40)

    apparently the answer when worked comes to .103 m but i doesnt seen to work for me! can anyone get it
    thanks for any help in advance

    I presume theres an extra set of brackets after the e to the power of bit - ie its not just e^-1000.

    Anyway I punched it into derive for you and got 0.09278289675

    sure you produced the equation properly?
    I'm assuming that its a dynamics equation..
    Any chance you could write it out and scan it, or do it up in word or something.. Its kinda hard to make it out..
