two forces of 14and 30 act on a body forming an obtuse angle w/ eachother. if the resultant is 60, whats the angle betweeen the 2 forces?

  • aleg/trig -

    The magnitude of the resultant of two forces are at a maximum when the angle between them is zero, when it equals the sum of the individual magnitudes, i.e.
    for forces A and B, the magnitude of the resultant is |R|=|A|+|B|.

    In this case, |A|+|B|=14+30=44 < 60, so it is impossible to have a resultant of 60. Please check for typos.
