  1. Jul 30, 2009 #1
    given a distance s = 8.6m, time t = 2s, and a mass = 1.01kg, evaulate the expression to a physically appropriate accuracy?

    m3 = 1.013 = 3.03kg

    is this correct

    I don't know if I understand what they ask. Do they ask for [tex]m^3[/tex], where m is the mass? If so, check out the units that you got. They are wrong. [tex](1.01 kg)^3=[/tex]?
    I don't see the point of s=8.6 and t=2s though.
