  • 'thata'

  • How many forces are acting on that object? 2 or 3? F1, F2 or/and W?

    I am not sure if W is on of the forces?

    What is the reason that the body falls?

  • YOU SAVE MY LIFE! THANK YOU!

  • your the man...the math man.

  • @lapibarg

    Simply looking at the problem will tell you the answer to that.. The total force must be greater than either individual, which leaves only A and D as choices.

    The total must also take in to account direction. You have some force N and some E, not all E, so it must be D.

    To solve this without choices, just use Pythagorean theorem for the magnitude, and work with the directions to find angle.

  • tnx

  • Forces of 479 lbs and 269 lbs act on a body. The smaller force acts due north; the larger force acts N 47.9E. Find the direction and magnitude of the resultant.

    A) 689 lbs, N 0E

    B) 359 lbs, N 16.8E

    C) 359 lbs, N 0E

    D) 689 lbs, N 16.8E
