    Read OP's title. It is trivial to calculate arc length. But the equations you wrote are wrong. It should be Z/360 instead of 360/Z and Y/360 instead of 360/Y.

    Can this problem be solved using Linear Algebra? Proof type problem.

    A, B and C are constants. It can be proven using trig that theta=-80 for all positive real values of A, B, C that make the three equations true. In other words, for the given conditions, theta must be equal to -80 for all three equations to be true, if theta is not equal to -80 at least one...

    pickup truck crash, would you want toolbox stored up against the cab, or at the back?

    ? Why do you think the other posters meant "the toolbox has a shorter impact time and thus a higher impulse"? Unequal forces can produce equal impulses.

    The lack of comprehension shown in this thread is pretty sad. The video and physorg article clearly state force from ultrasonic equipment is used. Even a first grader can read it and understand. Blowing air is not used or mentioned in video or article. Perhaps stuff like this is too...
