Homework Help: A little help please

    Heres the question – :bugeye:

    √ x + 4/3 y
    √ p
    (this whole equation should be squared, but not sure how to make the square root symbol big enough)

    p = 3.4 e3 Kg m-³

    x = 1.6 e11 N m-²

    y = 6.4 e10 N m-²

    I need to calculate the answer and give my answer in Km s-1 (Km per second)

    Any ideas??????? :confused:

    I don't understand.... are you just trying to substitute them in?

    If the problem is with the units, just use base units all the way through (kg, m, s) and then your final answer will be in m/s. Then its easy to convert m/s to km/s.
