what displacement must be added to a 50 cm displacement in the +x direction to give a resultant displacement of 85 cm at 25 degrees?
(i know the ans, just need to know how to get the ans)

  • Physics -

    Take the resultant, figure the vertical and hoizontal component of the resultant.

    vertical 85sin25
    horizontal 85 cos25

    So the added displacement must supply
    vertical 85 sin 25
    horizontal 85 cos25 -50cm

    use these components to get the displacement and angle.
