the vertical component of a force is200N . The force makes an angle of 30° with the horizontal. calculate the force

asked by amit
  1. F sin 30 = 200 N

    |F| = 400 N

    F = 400 cos 30 i + 400 sin 30 j
    or since you did not say what quadrant the force is in
    F = 400 cos 30 i - 400 sin 30 j
    or
    F = -400 cos 30 i + 400 sin 30 j
    or
    F = -400 cos 30 i - 400 sin 30 j

    I assume that amit means at MIT ?
