    What is the mathematical definition of the impulse?

    Show us the equation(s). That would be what you should have put in the "Relevant Equations" part of the Homework Help Template above...

    Then tell us what you think you should do with the equation(s). That would go in the last part of the HH Template...

    Is this correct??

    ΔPx = m(Vfx - Vix) = .60(-v sin 65 - v sin 65)

    = -2mvsin65

    -2(.60)(5.4)(.90) = - 5.8


    Ok now im gettin stuck?
