    M= 10 pounds
    A= 761 miles per hour
    What's the force in pounds?

    Force is measured in Newtons, not pounds.

    A is acceleration. Not speed. Also, your mass is wrong because...


    Pound is also a unit of force. It's not a unit of mass.

    Okay, in that case
    How much force would there be behind a supersonic punch from a fist that weighs 2kg?

    The way mathematical notation works, variables that are right next to each other are multiplied together. Just learn to use a calculator for multiplication and you'll be able to figure it out for yourself.

    Well we have a mass now, but you still gave us a speed instead of an acceleration. Just being at a certain speed has no force associated with it. If you really want to use speed we also need the time that it takes to reach that speed.

    Time it takes to reach that speed is 13 seconds.

    Then we've got F = 2 kg * 340.29 m/s / 13 s
    That gives us about 52.31 newtons or 11.76 pounds.

    With that amount of force it would take a 1000 kg car about 9 and a half minutes to reach highway speed.
